    We need to find the descent of feet per sec.

    To find this, use the same thing as miles per hour

    Distance / time=speed

    Red: 20:8=2.5m/s

    Blue:24:12=2m/s

    Therefore the blue one descends the slowest

    Find the unit rate of each by dividing distance by time:

    20 / 8 = 2.5 feet per second

    24/12 = 2 feet per second

    The blue parachute is falling slower.
