Question

Some students washed 24 cars in 2 hours. how many cars can they wash in 15 hours?

Answer 1

Car washed in 1 hour =24/2=12 so car washed in 15 hours= 15×12=180

Answer 2

Answer would be 180 cars.

Reason being if you take 24 and divide that by 2 you will get 12 and 12 times 15 is 180 or you could also do 24 times 7 then add 12 to get the 180 also
