Traviling upstream on the Mississippi River, a barge travels 56 mi in 7 h. Downstream, it travels the same distance in 4 h. Find the rate of the barge in still water and the rate of the current
Traviling upstream on the Mississippi River, a barge travels 56 mi in 7 h. Downstream, it travels the same distance in 4 h. Find the rate of the barge in still water and the rate of the current
56 /7 = 8 mph - its speed upstream
56 / 4 = 14 mph - its speed downstream
[8 + 14] / 2 = 11 mph - its speed in still water.
[14 - 8] / 2 = 3 mph - the rate of the current.
