Question

A machine produces 255 bolts in 24 minutes. At the same rate,how many bolts would be produced in 40 minutes?

Answer 1

425 bolts

Explanation:

255/24=x/40

cross product

24*x=255*40

24x=10200

x=10200/24

x=425

Answer 2

It could produce 425 bolts in 40 minutes.

First I found the unit rate by doing 255/24=10.625

Then I just multiplied that by 40 and got the answer.
