If the speed of the stream is a km/hr, then the time taken by Prosantamajhi to cover d km in downstream and upstream is t hours.

If the velocity of the stream is 2 km/hr, then the time taken by Ratanmajhi to cover 21 km in downstream and upstream is 10 hours.Hence find the required quadratic equation.

The ratio of the speed of a boat in still water and the speed of the stream is 5:1. If the speed of travelling downstream is 24 km/hr, then find the time taken by boat to cover 48 km while moving upstream

Speed of the stream is 3 km/hr and the upstream speed is 7 km/hr. Find the time taken by boat to cover 91 km downstream.

What will be speed of stream, if speed of boat in still water is 45km/hr? A. The time taken by boat to cover 240 km upstream is 4 hours more than time taken by boat to cover same distance in downstream. B. Boat takes total 15 hours to cover 300 km in downstream and upstream.

The downstream speed of a boat is 42 km/hr and the speed of current is 3 km/hr. What is the total time (in hours) taken by the boat to cover 72 km upstream and 84 km downstream?

The downstream speed of a boat is 20 km/hr and the speed of current is 5 km/hr. What is the total time (in hours) taken by the boat to cover 80 km upstream and 100 km downstream?

A steamer goes downstream from one point to another in 9 hours. IF covers the same distance upstream in 10 hours. If the speed of the stream be 1 km/hr, find the speed of the steamer in still water and the distance between the ports.
