Question

The boat moves 138 miles every 3 hours. How far does it move in 10 hours?

Answer 1

proportions can be used to solve this question


`(138)/(3) = (m)/(10)`
cross multiply 138 by 10 and then divide by 3. you will get 460.

proportions work because you set each side equal to each other using the fraction symbol. think about if 138miles is 3hours, then 10 hours is ???. 460.

Answer 2

460 would be my answer
