Speed of a boat along and against the current are 14 kms/hr and 8 kms/hr respectively. The speed of the current isA11 km/hrB6 km/hrC5.5 km/hrD3 km/hrAnswer: D. 3 km/hr Read Explanation: Solution:Given:Rate of Downstream = 14 km/hrRate of Upstream = 8 km/hrCalculation:Speed of Current = 12\frac{1}{2}21 (Rate of Downstream - rate of Upstream)=12(14−8)=\frac{1}{2}(14-8)=21(14−8)=62=\frac{6}{2}=26=3km/hr=3 km/hr=3km/hrSpeed of Current = 3 km/hr.
