Question
Peter, John and Mike run around a Circular track
starting from the same point simultaneously and in the same direction at the speed of 36 kmph, 54 kmph and 72 kmph respectively. If the length of the track is 3600 metre, when will Peter, John and Mike meet at the starting point for the first time after they start the race?Solution
- The boat's downstream and upstream speeds are 24 km/hr and 16 km/hr respectively. If the time taken to cover a distance of (x + y) km upstream with stream ...
A boat takes 20 hours to go 200 km upstream. If the boat doubles its speed, it can cover 200 km downstream in 4 hours. Find the speed of the stream.
The ratio of the speed of boat in upstream to speed of boat in downstream is 7:9. If the boat can cover a total of 70 km upstream and 90 km downstream i...
