A Boat On A River Travels Between Two Points 50 Miles Apart In One Hour The

A boat on a river travels between two points, 50 miles apart, in one hour. The return trip against the current takes 2 1/2 hours.

1. What is the boat’s speed in still water?
2. How fast does the current in the river flow?

Thank you. Been stuck on this one for a while.

Solution

50 = 1(r + c)

50 = 2.5(r – c)

Can you solve for c and answer?
