In one hour, a boat goes 11 kmph along the stream and 5 kmph against the stream.
Question 1:
In one hour, a boat goes 11 kmph along the stream and 5 kmph against the stream. The speed of the boat in still water (in kmph) is :
A.
3 kmph
B.
5 kmph
C.
8 kmph
Feedback
Speed in still water = 1/2(11 + 5) kmph = 8 kmph.
D.
9 kmph

A boat can travel with a speed of 13 km/hr in still water. If the speed of the stream is 4 km/hr, find the time taken by the boat to go 68 km downstream.
A man can row upstream 10 kmph and downstream 20 kmph. Find the man rate in still water and rate of the stream.
A man's speed with the current is 15 km/hr and the speed of the current is 2.5 km/hr. The man's speed against the current is:
A man takes 20 minutes to row 12 km upstream which is a third more than the time he takes on his way downstream. What is his speed in still water?
Speed of a boat in standing water is 9 kmph and the speed of the stream is 1.5 kmph. A man rows to a place at a distance of 105 km and comes back to the starting point. The total time taken by him is:
In one hour, a boat goes 11km along the stream and 5 km against it. Find the speed of the boat in still water
A boat runs at 22 km per hour along the stream and 10 km per hour against the stream. Find the ratio of the speed of the boat in still water to that of the speed of the stream.
In one hour, a boat goes 11 kmph along the stream and 5 kmph against the stream. The speed of the boat in still water (in kmph) is :
A boat sails 15 km of a river towards upstream in 5 hours. How long will it take to cover the same distance downstream, if the speed of the current is one-fourth the speed of the boat in still water:
Speed of a boat in standing water is 9 kmph and the speed of the stream is 1.5 kmph. A man rows to a place at a distance of 105 km and comes back to the starting point. The total time taken by him is:
