Question

The speed of boat in clan water is 30km/h. A boat takes the same time to travel 10km upstream as it does to travel 15km downstream. Find the speed of river current. . Answer it fast..

Answer 1

Answer:

Step-by-step explanation:

x-30kmph

Speed upstream=1/(x-y)

speed downstream=1/(x+y)

10/(30-y)=15/(30+y)

450-15y=300+10y

25y=150

y=6kmph
