The ratio of the speed of boats ‘A’ and ‘B’ in still water is 8:9, respectively. The speed of the current is 25% of the speed of boat ‘A’ in...
The Ship's speed in calm water exceeds that of the current by 20%. After sailing downstream for 4 hours, it traveled upstream for 4 hours with an increa...
The speed of a motorboat in still water is 50 km/hr. If the motorboat travels 120 km along the stream in 1 hour 30 minutes, then the time taken by it t...
A boat takes 5 hours longer to travel 15 km upstream than it does to travel 20 km downstream. The speed of the boat in still water is 5 km/hr. Calculate...
A boat can cover 195 km in downstream in 10 hours and 140 km in upstream in 14 hours. Find the distance travelled by the boat in still water in 4 hours.
A boy can swim a certain distance downstream in 2 hours and return in 5 hours. If the rate of stream is 3 kmph then what is the speed of boy in still wa...
Find the total distance covered by boat in still water in 8 hours if the speed of boat in upstream and in downstream is 10 km/h and 15 km/h respectively?
Speed of boat is 20 km/hr. Speed of the stream is 15% less than speed of boat. Then find time taken by boat to go 74 km downstream?
Speed of a boat in still water is 5 times more than the speed of stream. If boat covers 147 km in downstream in 7 hours, then find the time taken by the...
