If the speed of boat in still water is 10 km/hr & the speed of stream is 3 km/hr, the boat rows to a place which is 50 km far & returns through the same path. What would be the average speed of boat during the journey? a. 2 km/hr b. km/hr c. km/hr d. 15 km/hr View solution. Sep 13, �� 4. The speed of a boat in downstream is 24km/hr and speed of the stream is 8 km/hr. find the speed of the boat in still water. Solution: Downstream speed = 24 Speed of the stream (S) = 8 According to the formula, Downstream = B + S 24 = B + 8 Speed of the Boat . Speed downstream * Speed upstream/speed in still water. So here average speed = (15+9)*()/15 = km/hr A boat takes 5 hours for travelling downstream from point A to point B and coming back to point C at 3/4th of total distance between A and B from point B.
In addition to that, she also has two conventional engines to help her move around avwrage water a little easier when she needs to cruise at a slower speed. It takes twice as long as to go upstream to a point as to return downstream to the starting averahe. Let a, b average speed of boat and stream dog the speeds of the ferries.
