Aball rolls 12 meters in 4 seconds. what is the average speed of the ball?

1. 3 meters/seconds
2.8 meters/seconds
3.16 meters/seconds
4.48 meters/seconds

3 meters/second

Explanation:

Speed is roughly defined as distance travelled over a unit of time. So we can calculate the speed of the ball using the formula:

where:

s = speed

d = distance

t = time

Given:

d=12 meters

t = 4 seconds

So we plug that in our equation:

first one is the correct answer

the answer would be c
