The speed of a boat in still water is 8 km/hr and speed of current is 3 km/hr. If time taken to cover a certain distance upstream is 11 hours, then how ...
A boat can travel 36 km downstream in 45 min. The ratio of the speed of the boat in still water to the speed of the stream is 5: 1. How much time will t...
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 Boy can swim 12 km/hr in still water. If the velocity of the stream is 6 km/hr, the time taken by him to swim a place 28 km upstream and back is
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...
The speed of current is 10 km/hr. If the speed of the boat in still water had been 8 km/hr more than the original speed, then it would take 7 hours to c...
The ratio between the speed of the boat in upstream and the speed of the stream are 6:5 respectively. The boat can cover (d+140) km distance in downstre...
