The correct answer is D
The speed of a boat downstream is 20% more than the speed of the boat in still water. If the boat can travel 1280 km upstream in 16 hours, then find the...
A man can row at 36 km/hr in still water. In a stream which is flowing at 12 km/hr, it takes him 3 hrs to a place and back. How far is the place?
A takes 3 hours more while swimming upstream than downstream. His speed in still water is 12 km/hr. The speed of stream is 4 km/hr. What is the distance?
Speed of boat is 20 km/hr. Speed of the stream is 20% less than speed of boat. Then find time taken by boat to go 90 km downstream.
A boat covers a certain distance upstream in 6 hrs and comes back to starting point with current in 3 hrs, If boat's upstream speed is 15 km/hr, then, f...
Boat ‘A’ can cover 160 km in still water in 8 hours. In still water, if the ratio of the speed of boat ‘A’ to that of ‘B’ is 2:3 and the spe...
The speed of a boat in still water is 16/ 3 km/ h. It was found that the boat takes thrice as much time to row up as it does to row down the same distan...
A boat takes 15 hours to travel 360 km downstream. If it takes 18 hours to travel 288 km upstream, Determine the speed of the str...
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...
Speed of a boat in still water to speed of boat in upstream is 13:10. If the boat can travel 320 km in downstream in 5 hours, then find the time taken b...
