To find: The speed of current.
Answer to Problem 27AYU
Speed of current is
Explanation of Solution
Given information:
Speed of motorboat is
Boat makes a trip of
Calculation:
As per the given information −
Speed of motorboat is
Let us suppose speed of current is
Boat makes a trip of
While going upstream speed of current is subtracted and while going downstream speed of the current gets added in the speed of the boat.
Total time taken during upstream and downstream is
This can be written mathematically as -
Hence, speed of current is
