A Motorist's Average Speed Calculation

Calculation of Average Speed

A motorist travels 406 km in a 7.0-hour period. What was the average speed in km/h and m/s?

Answer:

Average speed of the motorist: 58 km/h and 16.1111 m/s

Explanation:

To calculate the average speed, we divide the total distance traveled by the total time taken.

So, average speed = Total Distance / Total Time

Given that the motorist traveled 406 km in 7.0 hours, we can calculate the average speed as:

406 km / 7.0 h = 58 km/h

To convert the average speed to m/s, we know that 1 km/h is equal to 0.277778 m/s:

58 km/h x 0.277778 = 16.1111 m/s

Therefore, the average speed of the motorist is 58 km/h and 16.1111 m/s.
