Let the speed of stream be ‘x’ km/hr. So, speed of boat in still water = 5 × x = 5x km/hr Downstream speed of boat = 5x + x = 6x km/hr According to question; 6x = 72/6 = 12 Or, x = 2 Upstream speed of the boat = 5x – x = 4x = 4 × 2 = 8 km/hr Required time taken = 88/8 = 11 hours
Speed of a boat in still water is 9 kmph and speed of stream is 6 kmph. A man rows to a place at a distance of 30 km and come back to starting point. Th...
Time taken by a boat to cover 253 km upstream is 49.99 % more than the time taken by the boat to cover 340 km downstream. Total time taken in covering b...
The speed of the boat in still water is 40% less than the speed of the boat in downstream. The time taken by the boat to cover 468 km distance in upstre...
The speed of the boat upstream and downstream are in the ratio of 3:4. If the boat covers a distance of 147 km in still water in 7 hours, determine the...
A man rows upstream 10 km and downstream 15 km taking 5 hours each. Find the speed of current.
...
Speed of a boat in still water is three times the speed of the boat in upstream. If the boat takes 35 minutes to cover 35 km in downstream, then find th...
A boat can cover 210 km in downstream in 10 hours and 160 km in upstream in 8 hours. Find the distance travelled by the boat in still water in 6 hours.
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 4:3 and the spe...
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.
The speed of a boat in still water is 16/5 km/ h. It was found that the boat takes thrice as much time to row up as it does to row down the same distanc...
