The speed of a boat in still water in 15 km/hr and the rate of current is 3 km/h

Question

The speed of a boat in still water in 15 km/hr and the rate of current is 3 km/hr. The distance travelled downstream in 12 minutes is:

Options:

A . 1.2 km

B . 1.8 km

C . 2.4 km

D . 3.6 km

Answer: Option D

Speed downstream = (15 + 3) kmph = 18 kmph.

.Distance travelled = \(\left(18\times\frac{12}{60}\right)km\) = 3.6 km
