Formula for Upstream and Downstream?
If the Speed of a Boat in Still Water Is U Km/Hr and the Speed of the Stream Is v Km/Hr, Then: Speed Downstream = (U + V) Km/Hr. Speed Upstream = (U - V)...
If the speed of a boat in still water is u km/hr and the speed of the stream is v km/hr, then: Speed downstream = (u + v) km/hr. Speed upstream = (u - v) km/hr.
How do I find upstream and downstream?
Upstream and Downstream – Formula
- Upstream = (u−v) km/hr, where “u” is the speed of the boat in still water and “v” is the speed of the stream.
- Downstream = (u+v)Km/hr, where “u” is the speed of the boat in still water and “v” is the speed of the stream.
- Speed of Boat in Still Water = ½ (Downstream Speed + Upstream Speed)
What is the formula of upstream?
The upstream speed is = b – r = 13 – 4 = 9 km /hr. Therefore using this in the formula for speed, we have: Time = 81/9 = 9 hr = (9 × 60) minutes = 540 minutes.
