H=height of ostrich
k=height of kiwi
h is 20 more than 4 times k
k=20+4k

k=108
108=20+4k

The basketball fell at rate of 9.8 feet per second

Step-by-step explanation:

The rate is the distance per unit time

Here

Distance = height = h = 53.9 feet

time = t = 5.5 sec

The rate will be given as:

$Rate = \frac{Height}{time} = \frac{h}{t}\\= \frac{53.9}{5.5}\\= 1.78\\$

Hence,

The basketball fell at rate of 9.8 feet per second
