Question

A man rows to a place 42 km away and comes back to the starting point. If the speed of the stream is 2 km/hr and the speed of the boat in still water is 5 km/hr. Then what is the total time taken by him?

Q: A man rows to a place 42 km away and comes back to the starting point. If the speed of the stream is

42/((5+2)) + 42/((5-2)) = 6 + 14 = 20 hrs

A 16 hrs

B 17 hrs

C 20 hrs

D 30 hrs

E 25 hrs

The downstream speed of a boat is 6 km/hr more than its upstream speed and the ratio of the speed of the boat in still water to the speed of the stream is 10:3. Find the total time taken by boat to travel 52 km downstream and 42 km upstream?
A boat goes 5 km an hour in still water, but takes twice as much time in going the same distance against the current. The speed of the current (in km/hour) is :
If the sum of upstream and downstream speed is 20 km/hr and the speed of the current is 5 km/hr. Then find time taken to cover 45 km in downward?
The speed of the stream is 11 km/h. Boat ‘A’ covers 84 km distance against the stream in 6 hours and boat ‘B’ covers 90 km distance against the stream in 3 hours. The speed of boat ‘B’ in still water is how much percent of the speed of boat ‘A’ in still water?
