A ship, when moving against the current, can travel a distance of 240 km in 8 hours. If the ship's speed in calm waters is 40 km/hr, how many hours will...
- A boat covers 90 km downstream and 70 km upstream in a total time of 10 hours. How much time will it take to travel 126 km downstream and 98 km upstream?
The speed of a boat in still water is 20 km/h, and the speed of the river flow is 4 km/hr. If the total time taken for the boat to go from point 'X' to ...
In still water, a boat can cover 30 km in 90 minutes. Speed of the stream is 20% of the speed of the boat in downstream. Find the time taken by the boat...
The speed of the boat in still water is 10 km/hr and the speed of the stream is 5 km/hr. A boat goes 75 km downstream with its usual speed but at the ti...
A man can row 32 km/hr in still water. It takes him thrice as long to row up as to row down the river. Find the rate of the current.
Boat speed in still water = 12 km/h, stream speed = 3 km/h. Time to go 30 km downstream and return 30 km upstream?
The speed of a boat in still water is twice the speed of the current. The difference between downstream and upstream speeds is 16 km/h. If the boat spen...
A boat running downstream covers a distance of 45 km in 3 hrs while it covers the same distance upstream in 5 hrs. Then speed of the boat in still water is
A boat's speed in calm water exceeds the speed of the current by 12 km/hr. Given that the current's speed is 1.25x km/hr and the boat takes 5 hours to t...
