Julie and Eric row their boat (at a constant speed) 21 miles downstream for 3 hours, helped by the current. Rowing at the same rate, the trip back against the current takes 7 hours. Find the rate of the current. ▸ 3 mph ▸ 2 mph ▸ 5 mph ▸ 1.5 mph Title: Julie and Eric row their boat (at a constant speed) 21 miles downstream for 3 ...

Julie and Eric row their boat (at a constant speed ) 48 miles downstream for 4 hours, helped by the current. Rowing at the same rate, the trip back against the current takes 10 hours. Find the rate of the current.

When going downstream the rate of speed was rowing speed 'r' plus the speed of the current 'c' When returning against the current the rate of speed was the rowing speed 'r' minus the current 'c' {See attachment} Therefore the rate of current is 8.4 miles/hr |
