  1. &GUIDECATIUTICUTPREPÅUTION a. Speed = Distance/ Time b. If a boat is moving in the direction of stream, its speed will be (speed of boat + speed of stream)and it will be called its Downstream Speed. c. If a boat is moving against the direction of stream. Its speed will be (speed of boat - speed of stream) and it will be called its Upstream Speed. d. Boat Speed = h (Downstream Speed + Upstream Speed) e. Stream Speed = 1/2 (Downstream Speed - Upstream Speed) f. Boat Speed, Man Speed are same. Similarly Stream Speed, Current Speed are same. 1. The upstream and downstream speed of a boat are 12 km/hr. and 18 km/hr respectively. Find the speed of the boat in still water and the rate of the stream. c)15 & 3 d)10 & 5 2. A boat moves down stream at the rate of 1 km in 6 minutes and upstream at the rate of 1 km in 10 minutes. Find the speed of current? 3. The speed of a boat in steel water is 4 km/hr. and the speed of current is 2 km/hr. If the time taken to reach a certain distance upstream is 9 hrs, find the time it will take to go the same distance downstream. 4.
