Answer & Explanation

 

  1. Rahul takes 400/3 % more time to cover a distance in upstream as compare to cover same distance in downstream. If his friend’s speed and his speed are in ratio 6 : 7, when they go in downstream, then find the ratio of speed of Rahul and his friend in still water. (Speed of stream is same in both cases)

(a) 4 : 5

(b) 5 : 4

(c) 7 : 6

(d) 3 : 5

(e) 6 : 7

Answer & Explanation

 

  1. A boat goes a certain distance downstream and then returns and covers 40% of distance covered in downstream. Ratio of time taken in covering downstream and upstream distances is 3 : 2. If speed of boat in still water is reduced by 50% then it covers 60 km downstream in 10 hours. Find the speed of boat in still water.

(a) 9 km/hr

(b) 8 km/hr

(c) 6 km/hr

(d) 10 km/hr

(e) 12 km/hr

Answer & Explanation

 

  1. A boat takes half time in moving a certain distance downstream than upstream. The ratio of the speed of the boat in still water and that of the current is :

(a) 2 : 1

(b) 4 : 3

(c) 1 : 2

(d) 3 : 1

(e) None of these

Answer & Explanation

 

  1. Distance between two points A and B in the river is 300 km and the river is flowing from point A to B. Two boats P and Q start from point A and B respectively towards each other, if Speed of boat P and boat Q in still water in 25 km/h and 15 km/h respectively and when they meet it is found the difference between the distance covered by boat P and Q is 150. Find the speed of current of the river.

(a) 15 km/h

(b) 5 km/h

(c) 2.5 km/h

(d) 2 km/h

(e) 5 km/h

Answer & Explanation

 

  1. If sum of upstream and downstream speed of boat is 72 km/hr. and if the boat travels 105 km upstream in 3 hours 30 min., then find the time taken to travel 126 km downstream

(a) 3 hours

(b) 3 hours 20 min

(c) 2 hours

(d) 2 hours 32 min

(e) None of these

Answer & Explanation

 

  1. A boat moves downstream at the rate of 1 km in 15/2 minutes and upstream at the rate of 5 km an hour. What is the speed of the boat in the still water?

(a) 8 km/hr

(b) 13/2 km/hr

(c) 4 km/hr

(d) 7/2 km/hr

(e) 6 km/hr

Answer & Explanation

 

  1. If time taken to cover (D+11) km upstream is thrice the time taken to cover (D–3) km downstream. If ratio of speed of boat in upstream to the downstream is 3 : 7 and time taken to cover (D+18) km downstream is 2.5 hours what will be the speed of current?

(a) 4 km/hr

(b) 6 km/hr

(c) 8 km/hr

(d) 10 km/hr

(e) 12 km/hr

Answer & Explanation

 

  1. The speed of a boat in still water is 24kmph and the speed of the stream is 4kmph. The time taken by the boat to travel from A to B downstream is 36 minutes less than the time taken by the same boat to travel from B to C upstream. If the distance between A and B is 4 km more than the distance between B and C, what is the distance between A and B?

(a) 112 km

(b) 140 km

(c) 56 km

(d) 84 km

(e) 28 km

Answer & Explanation

 

  1. A river is flowing with a steady speed of 4 km/h. One rows his boat downstream in the river and then returns by rowing upstream in the same river. When he returns to the starting point, the total distance covered by him is 42 km. If the return journey takes 2 h more than his outward journey, then the speed of his rowing in still water must be

(a) 12 km/h

(b) 10 km/h

(c) 9 km/h

(d) 8 km/h

(e) None of these
