What is a Calculator of Average Speed?

A calculator of average speed is a tool used to determine the average speed of an object over a specific distance and time. This calculator simplifies the process of calculating average speed, providing quick and accurate results.

Professor Greenline from BrightChamps

How to Use the Calculator of Average Speed?

Given below is a step-by-step process on how to use the calculator:

 

Step 1: Enter the distance traveled: Input the distance traveled into the given field.

 

Step 2: Enter the time taken: Input the total time taken for the journey.

 

Step 3: Click on calculate: Click on the calculate button to get the average speed.

 

Step 4: View the result: The calculator will display the average speed instantly.

How to Calculate Average Speed?

To calculate average speed, use the simple formula:

Average Speed = Total Distance / Total Time

 

This formula divides the total distance traveled by the total time taken, providing the average speed over the journey.

Using inconsistent units

Green Checkmark Icon Indicating Correct Solutions in This Math Topic

Ensure that the distance and time units are consistent (e.g., kilometers and hours). Mixing units can lead to inaccurate results.

Mistake 2

Red Cross Icon Indicating Mistakes to Avoid in This Math Topic

Incorrectly interpreting average speed

Green Checkmark Icon Indicating Correct Solutions in This Math Topic

Average speed is a measure of overall speed over a journey, not the speed at any specific point. Avoid assuming it reflects speed variations.

Mistake 3

Problem 1

What is the average speed if a car travels 150 kilometers in 3 hours?

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

Use the formula: Average Speed = Total Distance / Total Time

Average Speed = 150 km / 3 hours = 50 km/h

Explanation

By dividing 150 kilometers by 3 hours, the average speed of the car is calculated to be 50 km/h.

Problem 2

A cyclist covers 90 miles in 6 hours. What is the average speed?

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

Use the formula: Average Speed = Total Distance / Total Time Average Speed = 90 miles / 6 hours = 15 mph

Explanation

Dividing the total distance of 90 miles by 6 hours gives an average speed of 15 mph for the cyclist.

Problem 3

How fast is a runner going on average if they complete a 10-kilometer race in 50 minutes?

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

Convert time to hours: 50 minutes = 50/60 hours ≈ 0.833 hours

Use the formula: Average Speed = Total Distance / Total Time

Average Speed = 10 km / 0.833 hours ≈ 12 km/h

Explanation

Converting 50 minutes to hours and dividing 10 kilometers by 0.833 hours results in an average speed of approximately 12 km/h.

Problem 4

If a train travels 300 kilometers in 5 hours, what is its average speed?

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

Use the formula: Average Speed = Total Distance / Total Time

Average Speed = 300 km / 5 hours = 60 km/h

Explanation

By dividing 300 kilometers by 5 hours, the average speed of the train is calculated to be 60 km/h.

Problem 5

An airplane flies 800 miles in 2 hours. Find the average speed.

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

Use the formula: Average Speed = Total Distance / Total Time

Average Speed = 800 miles / 2 hours = 400 mph

Explanation

Dividing the total distance of 800 miles by 2 hours gives an average speed of 400 mph for the airplane.
