Question 69
Speeds of a boat along the current and against the current are 16 km/hr and 12 km/hr respectively. What is the speed (in km/hr) of the current?
Solution
Downstream speed of boat = 16 km/hr
Upstream speed of boat = 12 km/hr
=> Speed of current (in km/hr) = $$\frac{1}{2}\times(16-12)$$
= $$\frac{4}{2}=2$$ km/hr
=> Ans - (B)
