v=400ft/52.4s

v≈7.63 ft/s  (to nearest tenth)

Answer:

7.6 ft/sec

Step-by-step explanation:

Given : 400 feet in 52.4 seconds

To Find : Express each ratio as a unit rate.

Solution:

Distance = 400 feet

Time = 52.4 seconds

So, 400 feet in 52.4 seconds

So, in 1 second = [tex]\frac{400}{52.4}[/tex]

                        = [tex]7.6335[/tex]

So, unit rate =7.6 ft/sec

Hence 400 feet in 52.4 seconds as unit rate is 7.6 ft/sec
