A parachutist descends 44 feet in 4 seconds. Express the rate of the parachutist's change in height as a unit rate.
Montano1993 [528]

The unit rate of the parachutist change in height is 11 feet per second.

   • In Mathematics, Unitary method is a technique for solving a question by first finding the value of a single unit and then finding the required value by multiplying the number by value of single unit .

   • We use unitary method to find the ratio of one thing with respect to other thing.

   • There are two types of unitary method one is Direct Variation and the other is Inverse variation.

We have the rate of descend as 44 feet in 4 sec.

So, in 1 second it will be = 44 / 4 = 11 feet.

Which is the unit rate.

Therefore, the unit rate of descend for the parachutist is 11 feet per second.
