Question

Skydiver descends at an average rate of 120 miles per hour. How many miles per second is he descending rounded to the nearest hundredth?

Answer 1

If the sky diver goes at a speed of 120 it is 100 rounded

Answer 2

                 (120 mile/hour) x (1 hour / 3600 seconds)

             =    (120 / 3600)  (mile-hour / hour-second)

             =   1/30  mile/second

             or     0.03 mi/sec
