Answer:
3.5 kmph is the speed of the boat.
Given:
The distance covered by the boat up the stream is 10 km
The distance covered by the boat down the stream is 5 km
The time taken in both travels is 6 hours.
The speed of the stream is 1.5 km/h
To find:
Speed of the boat in still water = ?
Solution:
The distance covered by the boat up the stream is 10 km
The distance covered by the boat down the stream is 5 km
The time taken in both travels is 6 hours.
The speed of the stream is 1.5 km/h
Using time = distance/speed, we get the following equation
Now with the equation solved we get two values x = 3.5, -1.
Now speed cannot be -1 therefore, the speed of the boat in still water is 3.5 kmph.
