The correct answer is D
The speed of a boat in still water is 30 km/hr. If the boat covers 160 km in upstream in 8 hours, then find the time taken by the boat to travel 120 km ...
Speed of a boat in still water is three times the speed of the boat in upstream. If the boat takes 20 minutes to cover 15 km in downstream, then find th...
A boat can travel 18 km downstream in 2 hours and 12 km upstream in 3 hours. What is the speed of the boat in still water?
The speed of a boat in still water is 6 km/hr and speed of current is 4 km/hr. If time taken to cover a certain distance upstream is 10 hours, then how ...
A man rows 40 km upstream and 60 km downstream in 8 hours. If the ratio of his upstream speed to downstream speed is 2:3, then find the time required to...
The ratio of the speed of the boat in upstream to that of in downstream is 3:4, respectively. If the speed of the current is 5 km/h, then find the speed...
A boat covers 30 km downstream in 60 minutes. If the ratio of the speed of the boat in still water to that of the speed of the stream is 8:4, respective...
A boat goes 60 km upstream in 4 hours and 50 km downstream in 2 hours, then the speed of the boat in still water is
A man can row 12 km/hr in still water. If the speed of the current is 3 km/hr, it takes 4 hours more in upstream than in the downstream for the same dis...
