the men are camping 45 miles due west and then go 60 miles directly north. if they can cover 18 miles a day how long will it take them to reach the railroad?

Assuming
(1) they can go straight crosscountry
(2) they camped due west of the railroad
then the must travel
√(45^2+60^2) = 15√(3^2+4^2) = 75 miles
so, it will take them 75/18 = 25/6 days
