Question

kohli takes 10 min to row 8 km upstream which is three times the time he takes to row 8 km downstream what is his speed in still water?
​

Answer 1

Answer: his speed is 2.4 km/min

Step-by-step explanation:

Let, his speed and water speed are x and y respectively

Then according to question,

8/(x+y) = 10/3

And 8/(x-y) = 10

x+y = 2.4 km/min

x-y = 0.8 km/min

Then x = 1.6 km/min and y = 0.8 km/min
