A motor boat can travel at 10 km/hr in still water. It travelled 91 km downstream in a river a then returned taking altogether 20 hours. Find the rate of flow of the river. `3\ k m//h r` b. `5k m//h r` c. `6\ k m//h r` d. `8\ k m//h r`

A motorboat can travel at 10 km/h in still water. It travelled 91km downstream in a river and then re- turned to the same place, taking altogether 20 h. The rate of flow of river is

The speed of a boat in still water is 10 km /hr. If it can travel 26 km downstream and 14 km upstream in the same time, the speed of the stream is : 2 k m//h r b. 3 k m//h r c. 4 k m//h r d. 2. k m//h r

A boat covers 24 km upstream and 36 km downstream in 6 hours while it covers 36 km upstream and 24 km downstream in 6 1/2 hours. The velocity of the current is 1 k m//h r b. 1. 5 k m//h r c. 2 k m//h r d. 2. k m//h r

A motor boat whose speed is 18km/h m still water takes 1 hour more to go 24km upstream than to return downstream to the same spot. Find the speed of the stream.

A car travelling with 5/7 of its actual sped covers 42 km in 1 hr 40 min 48 sec. find the actual speed of the car. 17 6/7k m//h r b. 25 k m//h r c. 30 k m//h r d. 35 k m//h r

A ,motorboat can travel 30 km upstream and 28 km downstream in 7 h. It can travel 21 km upstream and return in 5 h. Find the speed of the boat in still water and the speed of the stream.

Boat A travels downstream from Point X to Point Y in 3 hours less than the time taken by Boat B travel upstream from Point Y to Point Z. The distance between X and Y is 20 km, which is half of the distance between Y and Z. The speed of Boat B in still water is 10 km/h and the speed of Boat A in still water is equal to the speed of Boat B upstream What is the speed of Boat A in Still water? (Consider the speed of the current to be the same.) a. 10 k m//h b. 16 k m//h c. 12 k m//h d. 8 k m//h

A man can row 9 1/3 kmph in still water and finds that it takes him thrice as much time to row up than as to row down the same distance in the river. The speed of the current is : a. 3 1/3 k m//h r b. 3 1/9k m//h r c. 4 2/3k m//h r d. 4 1/2k m//h r

A journey of 192 km between two cities takes 2 hours less by a fast train than by a slow train. If the average speed of the slow train is 16 km/hr less than that of the fast train, then the average speed of the fast train is 32 k m//h r b. 48 k m//h r c. 36 k m//h r d. 64 k m//h r
