Times of the two trips are equal.

A boat moves upstream. What is the time taken to row a distance of 90 km. A boat goes 30 km upstream and 44 km downstream in 10 hours Video Example 19A boat goes 30 km upstream and 44 km downstream in 10 hours. If the speed of the water is 15 kmh then the speed ofthe boat in still water is.

In one hour a boat goes 11 km along the stream and 5 km against the stream. While going down stream the water current km hr gets added to boats speed and opposite when boat goes upstream ie boats speed is reduced by an amount of water current acting in opposite direction. A motor boat covers a certain distance downstream in a river in 3 hours.

Speed of boat in still water. Boats speed against the current is 12 - 4 8 mph. A man can row a boat at 10 kmph in still water and the speed of the stream is 8 kmph.

Thats 3 hours and 52 minutes and 30 seconds. So if speed of boat. A boat moves downstream at the rate of 1 km in minutes and upstream at the rate of 5 km an hour.

If the rate of the current is 9 kilometers per hour find the rate of the boat in still water. If the speed of the stream is 4 kmhr find the time taken by the boat to go. In this case the net speed of the boat is called the upstream speed.

A boat moves upstream at the rate of 1 km in 20 minutes and down stream 1 km in 12 minutes. Stream The moving water in a river is called a stream. Aptitude Questions Boats and Streams.
