Prakash can swim at a speed of 32 km/h upstream and 44 km/h downstream. What is the speed of the current?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is Option 3 i.e. 6 km/h.
Let's assume the speed of Prakash is x and the speed of the current is y.
His downstream speed:
x + y = 44..........1
Upstream speed
x - y = 32............2
Equation 2 is subtracted from Equation 1
x + y - x + y = 44 - 32
2y = 12
y = 6 km/h
Speed of the current = 6 km/h
