The ratio of swimming time taken by Rahul to go 10 km upstream to 10 km downstream is 11:5. Calculate the ratio of swimming speed of Rahul in still water to the speed of river flow.
Mayan swims in still water at the rate of 6 kmph. When he swims in a stream, he takes twice the time to go upstream as he takes to go downstream. Calculate the speed of the current.
Manju swims 14 km upstream in same time as 26 km downstream. Calculate her speed in still water if the speed of the stream is 3 kmph.
Keerthi covers 36 km upstream and 24 km downstream in six hours 30 minutes. And just in 6 hours, he covers 36 km downstream and 24 km upstream. Find the rate of river flow.
Ravi can cover upstream at 10 kmph and downstream at 18 kmph. Calculate the speed of Ravi in still water and the speed of river.
Arul's speed in still water is 10 kmph and he takes 4 hours more while swimming upstream than downstream. The speed of the stream is measured as 2 kmph. Find the distance.
A stream flows at a speed of 6 kmph. Sundar swims some distance downstream in 12 hours and he returns covering the same distance upstream in 18 hours. Calculate the speed of Sundar.
Towns A, B and C are located at the bank of the river. Distance of B from A & C is same. Jeeva rows from A to B and from B to A in total 10 hours and he requires 4 hours to row from A to C. Calculate Jeeva's speed in still water.
Calculate the speed of the boat in still water and the speed of the river, if the boat takes 8 hours to row 48 km downstream and 12 hours to row the same distance upstream.
Ragu swims 20 km in 1 hour downstream and the same distance in 2 hours upstream. Calculate the speed of Ragu.
Faizal covers a distance of 20 km downstream in 2 hours and the same distance upstream in 5 hours. Calculate the speed of the boat in still water.
The speed of a man in still water is 20 kmph and the rate of current is measured as 5 kmph. Find the distance travelled downstream in 12 minutes.
A man can row a boat in still water at a speed of 7 kmph and it takes 6 hours more to travel the same distance upstream than in downstream. Find the distance between the two destinations.
If a boat's downstream speed is 34 kmph and its upstream is 22 kmph, then what is the speed of boat in still water?
If Ramya can swim 14 km upstream in same time as 26 km downstream, then what will be her speed in still water. And it is denoted that the speed of the stram is 3 kmph.
A man with the speed of 15 kmph in standing water can ride 30 km downstream and returns in a total time of 4.5 hours. Calculate the speed of the current.
The ratio of the swimming speed of Gayu's in still water to the speed of the stream is calculated as 7:1. She swims 4.2 km upstream in 14 minutes. Calculate the time she takes to swim 18.4 km downstream.
The speeds of the stream and the boat in still water are 6 kmph and 30 kmph respectively. Calculate the distance it can cover downstram in 24 mins.
Mathavi rows 30 kilometres upstream and 44 kilometres in 10 hours. And in 13 hours, she covers 55 kilometres downstream and 40 kilometres upstream. Calcuate the speed of the boat in still water.
The boat rowed 50 km downstream in 5 hours and 24 km upstream in 6 hours. Calculate the speed of the boat and the river.
A man can row 96 km downstream in 8 hours, whereas the speed of a stream is marked as 4 kmph. Calculate the time needed by a man to cover 8 km upstream.
In 11.25 minutes, a boatman can cover a distance of three quarters of a kilometer. Calculate the speed of the boat in still water.
The speed of the boat is marked as 14 kmph in standing water and the stream's speed is 1.2 kmph. What time does the boat need to cover a distance of 4864 km its and return.
Shilpa takes time twice as long as to swim upstream than to swim downstream. She swims at a speed of 12 kmph in still water. Calculate the speed of the river.
Damu swims in still water at a speed of 20 kmph. He swims 26 km downstream and 14 km upstream in same time. Find the speed of the stream.
