Question
- The speed of a boat in still water is 5km/hr. If the speed of the boat against the stream is 3 km/hr, what is the speed of the stream?1.5 km/hr2 km/hr2.5 km/hr1 km/hr
Solution
The speed of the boat in still water is the speed of the boat plus the speed of the stream. When the boat is going against the stream, the speed of the stream is subtracted from the speed of the boat.
Given: Speed of boat in still water (b) = 5 km/hr Speed of boat against the stream (a) = 3 km/hr
We can set up the equation as follows: b - s = a Where s is the speed of the stream.
Substituting the given values: 5 - s = 3 Solving for s, we get: s = 5 - 3 s = 2 km/hr
So, the speed of the stream is 2 km/hr.
