Answer:

Speed per second= 7.5 feet per second

Step-by-step explanation:

Giving the following information:

We have a distance (225 feet), and a time (30 seconds). Also, we know that the speed was constant.

All we have to do is divide the distance by the time and determine the speed per second:

Speed per second= distance / time

Speed per second= 225 / 30

Speed per second= 7.5 feet per second
