Question

Speed of a man in still water is 6 km/hr and the river is running at 4km/hr. The total time taken to go to a place and come back is 18 hours. What is the distance traveled?

Answer 1

Let the total distance be $d$

Speed in upstream = $2Km/Hr$

Speed in downstream = $10Km/Hr$

According to question , $\frac{d}{2}$+$\frac{d}{10}$=$18Hrs$

Solving we get $d=30Km$
So Total distance travelled = $60$Km
