Question

A parachutist's speed during a free fall reaches
207
kilometers per hour. What is this speed in meters per second? At this speed, how many meters will the parachutist fall during 5 seconds of free fall?

Answer 1

1) Convert using online calculators.
    207km/h = 57.5m/s

2) Use the rate from question 1.
    Make an equation and cross multiply to solve for x.
    57.5/1 = x/5
    x = 57.5(5)
    x = 287.5
    So he fell 287 meters in just 5 seconds
