Question

Sonny Toomey 16 seconds to finish a 100-m race. What was Sonny's average speed in the race? Give your answer in the decimal form.

Answer 1

6.25 m/s.

Step-by-step explanation:

Total distance travelled = 100 m

Total time = 16 s

Average speed =?

Average speed is simply defined as the ratio of total distance travelled to the total time taken to cover the distance. Mathematically, it is expressed as:

Average speed = total distance / total time

With the above formula, we can obtain the average speed of Sonny Toomey as illustrated below:

Total distance travelled = 100 m

Total time = 16 s

Average speed =?

Average speed = total distance / total time

Average speed = 100 / 16

Average speed = 6.25 m/s

Therefore, the average speed of Sonny Toomey is 6.25 m/s
