Find the total distance covered by boat in each upstream and downstream in 8 hours if the speed of boat in still water and speed of current is 26 km/h and 8 km/h respectively?
Speed in upstream = 26 – 8 = 18 km/hr Speed in downstream = 26 + 8 = 34 km/hr Required total distance= (18 + 34) × 8 = 416 km
If the sum of upstream and downstream speed is 20 km/hr and the speed of the current is 5 km/hr. Then find time taken to cover 45 km in downward?
The velocity of a boat when moving downstream is 18 km/h greater than the speed of the stream. If it takes the boat 8 hours to travel 192 km downstream,...
