Question 607317: A boat can travel at a constant rate of 15 miles per hour in still water. The total time taken to go upstream and return to the starting point is given by the function t = 60
15 - c
+ 60
15 + c
, where c represents the speed of the current.
If the speed of the current is 5 miles per hour, how many hours will the boat take to complete the trip? Answer by richwmiller(17219) (Show Source):
