Sam has already worked for 27.7 hours this week. He washes cars, and can wash a car in 2.5 hours. He wants to work over 60.2 hours this week.

The question is incomplete ; we could calculate the least number of cars he can still wash for the week expressed in inequality form.

x > 13 ; 13

Step-by-step explanation:

Given that :

Anticipated work hour for entire week = 60.2 hours

Hours worked = 27.7 hours

Rate of car wash = 2.5 per hour

Hours left to work for the week :

60.2 - 27.7 = 32.5

Hours left / unit rate of car wash

32.5 / 2.5

= 13

Hours worked +( hours left * unit rate) > anticipated hours

27.7 + 2.5x < 60.2

2.5x > 60.2 - 27.7

2.5x > 32.5

x > 32.5 / 2.5

x > 13

Hence ; Sam could still wash over 13 cars this week

the answer is 31.27mph
