Answer 1

Explanation:

Here we are asked to determine the unit rate for each one of the options given. By unit rate we mean the quantity for per unit quantity . Hence in order to find that we divide the two and quotient is our unit rate. Let us see how:

A. 420 miles in 7 hours

Unit rate =
`(420)/(7)`

Unit rate = 60 miles per hour

B. 360 customers in 30 days

unit rate =
`(360)/(30)`

Unit rate = 120 customers per day

C. 40 meters in 16 seconds

Unit rate =
`(40)/(16)`

Unit rate = 2.5 meters per second

D. $7.96 for 5 pounds

Unit rate =
`(7.96)/(5)`

Unit rate = $1.59 per pound
