Question
Solution
Sec2 θ ( 2 + tan2 θ + cot2 θ) ÷ (sin2θ – tan2θ) \ (cosec2θ + 2 + sec2 θ) (1 + cot2 θ)2 Put θ = 450 = 2(2 + 1 + 1) ÷ (1/2 – 1) / (2 + 2 + 2) (4) = 8 × -2 / 24 = - 2/3
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.
