Methane is the main component of natural gas, making up about 70-90% of its composition.
Speed of a boat in still water is 12 kmph and speed of stream is 9 kmph. A man rows to a place at a distance of 63 km and come back to starting point. T...
(√3364+ √484) – √2916÷ √1296 × √36 ÷ √64 = ?
A boat can cover 220 km in downstream in 10 hours and 170 km in upstream in 17 hours. Find the distance travelled by the boat in still water in 5 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...
A boat goes 56 km in upstream in 4 hours and takes 3 hours to complete a distance of 18 km in downstream. Find the speed of boat in still water.
Speed of a boat in still water is 6 times more than the speed of stream. If boat covers 144 km in downstream in 9 hours, then find the time taken by the...
The speed of boat downstream and upstream is 32 km/hr and 24 km/hr respectively. Time taken to travel a distance of (d + 55) km downstream and (e + 35) ...
Speed of a boat in still water to speed of boat in upstream is 11: 9. If the boat can travel 260 km in downstream in 10 hours, then find the time taken ...
The ratio of the speed of boat ‘A’ in still water, the speed of boat ‘B’ in still water and the speed of the current is 8:6:2, respectively. If ...
The ratio of the speed of a boat in still water to the speed of the stream is 4:1. If the boat takes 10 hours to cover 240 km downstream, find the total...
