A rocket is 1 mile above the earth in 30 seconds and 5 miles above the earth in 2.5 minutes. What is the rockets rate of change in miles per second? What about miles per minute.

Answer 1

1 miles 30 seconds

5 miles 2.5 minutes = 5 miles 150 seconds

4 miles change in 120 seconds

4/120 miles per second ---> 0.033 miles/second

4 miles change in 2 minutes

4/2 miles per minute ---> 2 miles per minute
