Question
What is the value of (4/3) cot2Â (p/6) + 3
cos2 (150o) – 4 cosec2 45o + 8 sin (p/2)?Solution
When travelling downstream, a boat takes 6 hours to travel 240 km. If the speed of the stream is (3/8)th of downstream speed of the boat, the...
Ratio of speed of boat in downstream and speed of stream is 7:4, if speed of current is 8 km/hr, then find distance travelled (in km) upstream in 7 hours.
A man swims 2km/h against the stream and goes 1 km in 10 minutes along the stream, how much time will it take to cover 5 km in still water?
A boat covers 13 km upstream in 52 min. If the speed of the current is 3 km / h, then in how much time will it cover 40 km downstream?
A boat can cover 130 km in downstream in 10 hours and 120 km in upstream in 8 hours. Find the speed of boat in still water
A boat goes 40 km in upstream in 5 hours and takes 3 hours to complete a distance of 18 km in downstream. Find the speed of boat in still water.
- Ratio of speed of a boat in still water to speed of stream is 14:2 respectively.Ratio of the time taken by the boat to cover a distance of (x + 42) km upst...
Speed of current is equal to 15% of speed of boat in still water. If the boat takes 3 hours to cover 120 km in still water, then find the time taken by ...
Two boats X and Y start towards each other from two places, 76 km apart. Speed of the boat X and Y in still water are 8 km/hr and 11 km/hr respectively....
Speed of a boat in still water is 15 kmph and speed of stream is 12 kmph. A man rows to a place at a distance of 54 km and come back to starting point. ...
