Respuesta :

A parachutist descends 65 feet in 5 seconds.

To find the unit rate, you need to find how many feet the parachutist descends per second(for 1 second)


You can divide 65 by 5 to get the # of feet per second.

65/5 = 13


13 feet per second

The problem tells us that in 5 seconds, the person descended 65 feet.

Therefore, we can calculate how many feet the person descended in one second:
[tex]x = 65 \div 5 \\ x = 13[/tex]

They descended 13 feet per second.
Because their altitude is decreasing, The unit rate would be negative: -13 feet per second
