Atropical storm has been moving at 15 miles per hour for the past two days. bess recorded that the storm moved 135 miles yesterday and 75 miles today. for how many hours has bess been keeping track of the storm?

1) in first place you need establish a relation of miles per hour , 15 miles / h

the total miles that Bess has been keeping track the storm is 75+135 =210

2) Now  15 miles ___ 1 h
