Question: A cyclist travels 30 km in 2 hours. What is the average speed in m/s?

Options:

Correct Answer: 4.17 m/s

Solution:

Average speed = Total distance / Total time = 30 km / 2 h = (30 * 1000 m) / (2 * 3600 s) = 4.17 m/s.

A cyclist travels 30 km in 2 hours. What is the average speed in m/s?

Step 1: Identify the total distance traveled by the cyclist, which is 30 km.
Step 2: Identify the total time taken by the cyclist, which is 2 hours.
Step 3: Convert the distance from kilometers to meters. Since 1 km = 1000 m, multiply 30 km by 1000 to get 30000 m.
Step 4: Convert the time from hours to seconds. Since 1 hour = 3600 seconds, multiply 2 hours by 3600 to get 7200 seconds.
Step 5: Calculate the average speed using the formula: Average speed = Total distance / Total time.
Step 6: Substitute the values: Average speed = 30000 m / 7200 s.
Step 7: Perform the division to find the average speed, which is approximately 4.17 m/s.

Average Speed – Average speed is calculated by dividing the total distance traveled by the total time taken.
Unit Conversion – Converting kilometers to meters and hours to seconds is essential for calculating speed in meters per second.
