Kareem Molina · Answer 1

75 cars.

Step-by-step explanation:

Let's use a ratio to solve:

minutes : cars

32 : 5

160 : 25

320 : 50

480 : 75

Since 480 minutes is 8 hours, and they get 75 cars washed in 480 minutes, then they have washed 75 cars in 8 hours.

Joanna Walsh · Answer 2

75 cars

Step-by-step explanation:

Convert the 8 hours into minutes, 480.

Divide by the 32 minutes, 15.

Multiply by the number of cars in 32 minutes, 5.

Answer is 75.
