Question

Speed of a boat along and against the current are 14 kms/hr and 8 kms/hr respectively. The speed of the current is

• A. 11 km/hr
• B. 6 km/hr
• C. 5.5 km/hr
• D. 3 km/hr

Answer 1

Answer:

D. 3 km/hr

Solution:

Given:

Rate of Downstream = 14 km/hr

Rate of Upstream = 8 km/hr

Calculation:

Speed of Current = $\frac{1}{2}$ (Rate of Downstream - rate of Upstream)

$=\frac{1}{2}(14-8)$

$=\frac{6}{2}$

$=3 km/hr$

Speed of Current = 3 km/hr.
