Question

If a tennis ball travelled 75 meters in 15 seconds, what is it's average speed?

Answer 1

The average speed of a tennis ball that traveled 75 meters in 15 seconds is calculated using the formula v = d/t, which results in an average speed of 5 meters per second.

Step-by-step explanation:

If a tennis ball traveled 75 meters in 15 seconds, we can calculate its average speed using the formula for speed, which is the distance traveled divided by the time taken to cover that distance. The average speed (v) is given by:

v = distance / time

In this case, the distance (d) is 75 meters and the time (t) is 15 seconds:

v = 75 m / 15 s = 5 m/s

Therefore, the average speed of the tennis ball is 5 meters per second.

The average speed of a tennis ball that traveled 75 meters in 15 seconds is calculated using the formula v = d/t, which results in an average speed of 5 meters per second.

Answer 2

5 m / sec

Step-by-step explanation:

the average speed (S) is calculated as

S =
`(D)/(T)` ( D is the distance travelled and T , the time taken )

here D = 75 m an T = 15 seconds , then

S =
`(75)/(15)` = 5

then average speed of ball is 5 m per second.
