A boat can travel 9.6 km downstream in 36 min . If speed of the water current is 10% of the speed of the boat in downstream . How much time will boat take to travel 38.4 km upstream .

A boat can travel 15 km downstream in 18 min. The ratio of the speed of the boat in still water to the speed of the stream is 4 : 1 . How much time will the boat take to cover 10 km upstream ?

A boat travels a distance of 50 km downstream in 5 h and 80 km upstream in 10 h. Find the speed of the boat and speed of the current.

A boat travels 64 km downstream in 16 hours and 12 km upstream in 8 hours. What is the speed (in km/hr) of boat in still water?

The ratio of the speed of a boat in still water and the speed of the stream is 5:1. If the speed of travelling downstream is 24 km/hr, then find the time taken by boat to cover 48 km while moving upstream

A boat travels upstream at the speed of 20 km/h and downstream at the speed of 30 km/h. What is the speed of the boat.
