A man swims downstream 81 km and upstream 45 km, taking 9 hr each time. Find the man’s rate in still water?  Â
A boat running downstream covers a distance of 32 km in 4 hrs and covering the same distance upstream in 16 hrs. What is the speed of a boat in still wa...
A boat's speed in still water allows it to cover 120 km in 8 hours. The current's speed is 20% of the boat's speed. How long will it take the boat to tr...
- A boat covers (x – 20) km upstream in the same time it covers (2x – 95) km downstream. If the speed of the boat and stream are 15 km/h and 3 km/h respe...
The duration it takes for boat 'P' to cover 160 km downstream is equal to the duration it takes to cover 120 km upstream. If the ratio of the speed of b...
A man swims 2km/h against the stream and goes 1 km in 10 minutes along the stream, how much time will it take to cover 5 km in still water?
A man rows upstream 10 km and downstream 15 km taking 5 hours each. Find the man’s speed in still water.
...The downstream speed of a boat is 6 km/hr more than its upstream speed and the ratio of the speed of the boat in still water to the speed of the stream ...
Ratio of speed of boat in downstream and speed of stream is 7:3, if speed of current is 9 km/hr, then find distance travelled (in km) upstream in 6 hours.
The speed of boat in still water is 48 kmph. If it takes 5 hour to go upstream 40 kms, in what time approximately will it return same distance downstrea...
