Question

Express each ratio as a unit rate. Round to the nearest tenth, if necessary. 400 feet in 52.4 seconds

Answer 1

velocity=distance/time

v=400ft/52.4s

v≈7.63 ft/s (to nearest tenth)

Answer 2

7.6 ft/sec

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 =
`(400)/(52.4)`

=
`7.6335`

So, unit rate =7.6 ft/sec

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