To find: The speed of current.
Answer to Problem 25AYU
Speed of current is
Explanation of Solution
Given information:
Speed of motorboat is
Boat makes an upstream trip in
Calculation:
As per the given information −
Speed of motorboat is
Let us suppose speed of current is
Boat makes an upstream trip in
While going upstream speed of current is subtracted and while going downstream speed of the current gets added in the speed of the boat.
Since distance covered upstream and downstream are same.
Hence, speed of current is
