Question

A boat traveled 165 kilometers each way downstream and back. The trip downstream took 5 hours. The trip back took 11 hours. Find the speed of the boat in still water and the speed of the current.

Answer 1

The speed of the boat in still water can be calculated by dividing the total distance traveled (165 km x 2 = 330 km) by the total time taken (5 hours + 11 hours = 16 hours). Therefore, the speed of the boat in still water is 330 km/16 hours = 20.625 km/hr.

The speed of the current can be calculated by dividing the total distance traveled (165 km x 2 = 330 km) by the total time taken for the downstream trip (5 hours). Therefore, the speed of the current is 330 km/5 hours = 66 km/hr.
