The speed of a boat in still water is 15 Km/hr and the rate of current is 3 Km/hr. The distance travelled downstream in 12 minutes is
Answer & explanation
Correct answer: option 2
Speed of boat in still water= 15 km/hr
Speed of stream/current = 3 km/hr
Downstream speed = 18 km/hr
According to the question:
18 = \(\frac{Distance }{12/60}\)
Distance = 18 x \(\frac{ 12}{60 }\)
Distance = 3.6 km
