# What Must Be Your Average Speed in Order to Travel 350 Km in 5.15 H?

To travel 350 km in 5.15 h, your average speed must be 67.8 km/h. This is calculated by dividing the distance you need to travel by the amount of time you have to travel it. In this case, you would need to maintain a speed of approximately 68 km/h for the entirety of your trip in order to reach your destination within the given time frame.

Assuming you are traveling by car, your average speed must be 67 km/h in order to travel 350 km in 5.15 h. This is based on the simple formula: distance = speed x time. To solve for speed, we divide both sides of the equation by time, which gives us: speed = distance/time.

Thus, if we plug in the given values of 350 km and 5.15 h, we get: speed = 350 km/5.15 h = 67 km/h.

### What is Average Speed for Class 9Th?

The average speed for class 9th is 50 km/h. This means that the average student in class 9th can ride their bicycle at a speed of 50 km/h.

## How Do You Find the Average Speed of a Motion?

A lot of people think that finding the average speed of a motion is difficult, but it really isn’t. All you need to do is take the total distance traveled by the object and divide it by the total time it took to travel that distance. That’s all there is to it!

Now, let’s say that you wanted to find the average speed of a car over the course of a 20-minute drive. The first thing you would need to do is figure out how far the car traveled during that time. Let’s say that it traveled 5 miles in those 20 minutes.

Then, all you would need to do is divide 5 by 20 and you would get your answer: 0.25 miles per minute, or 15 miles per hour. Of course, this method only works if the object in question is moving at a constant speed. If an object speeds up or slows down during its journey, things can get a little more complicated (but not too much!).

In these cases, you would need to break up the journey into smaller sections and find the average speed for each section separately before adding them all together to get an overall average speed for the entire journey.

## How Do You Calculate Average Speed Quizlet?

There are a few different ways to calculate average speed, but the most common is to take the total distance traveled and divide it by the total time taken. So, for example, if you travel 100 miles in 2 hours, your average speed would be 50 mph. You can also calculate average speed by taking the starting point and ending point of your journey and dividing the distance between them by the total time taken.

So, if you start at Point A and travel to Point B which is 100 miles away, and it takes you 2 hours to get there, your average speed would again be 50 mph. Another way to think about it is that average speed is equal to rate (distance traveled per unit of time). If you know your rate, then you can simply multiply that by the amount of time taken to find your average speed.

So, for example, if you travel at a rate of 30 mph for 2 hours, your average speed would be 60 mph. Finally, it’s worth noting thataverage speed is different from instantaneousspeed – which is simply the speed at any given moment during a journey. To calculate instantaneousspeed, you would need data on an object’s position at regular intervals throughout its journey (which isn’t always easy or possible to obtain).

#### Which One of the Following is True of an Object That is Said to Be Moving Slow?

The object is not moving.

#### A Car Travels 90 Km/H, How Long Does It Take for It to Travel 400 Km

If a car is travelling at 90 km/h, it will take approximately 4.4 hours to travel 400 km. This is because 400 km divided by 90 km/h equals 4.4 hours. Of course, this time may vary slightly depending on the exact speed of the car and other factors such as traffic and road conditions.

But generally speaking, it would take just over 4 hours to travel 400 km at 90 km/h.

#### A Motorist Travels 160 Km at 80Km/H And 160 Km at 100 Km/H. What is the Average Speed of

Assuming the motorist is traveling in a straight line, their average speed would be 90 kilometers per hour. This is because they would have traveled a total of 320 kilometers in 3.5 hours (80 km/h for 1.5 hours and 100 km/h for 2 hours).

#### When is the Average Velocity of an Object Equal to the Instantaneous Velocity?

The average velocity of an object is equal to the instantaneous velocity when the object is moving in a straight line at a constant speed. This means that the object’s velocity is not changing over time, and so its average velocity is the same as its instantaneous velocity.

#### Which of the Following Quantities Has Units of a Velocity?

There are many things in the world that have units of velocity. Here are some examples: The speed of a car is typically measured in kilometers per hour (km/h).

The speed of a plane is usually measured in kilometers per hour (km/h) or miles per hour (mph). The speed of sound is about 340 meters per second (m/s). So, which of the following quantities has units of velocity?

The answer is all of them! Velocity is a measure of how fast something is moving and can be expressed in many different ways. These are just a few examples – there are many other things that can be measured in terms of velocity as well.

## Conclusion

Assuming you’re travelling on a road without speed limits, the average speed you would need to travel in order to cover 350 km in 5.15 hours would be approximately 67.5 km/h. This is based on the simple calculation of distance divided by time.
