Question

The time taken for a boat to cover certain distance in upstream is equal to the time taken by the boat to
cover three times the distance in downstream. If the speed of current is
in still water?
in upstream is equal to the time taken by the boat to
the speed of current is 5 kmph, what is the speed of boat​

Answer 1

Answer:

10 km/hr

Step-by-step explanation:

let speed of boat be v

and the speed of current be u

a/c v+u = 3d/t.....(1)

and v-u = d/t.......(2)

putting the value of d/t in (1)

v+u = 3(v-u)

v=2u i. e v=10
