Speed of the boat = 15 km/h
Speed of the current = 3 km/h
Find the speed of downstream:
Speed of downstream = 15 + 3 = 18 km/h
Find the duration in hour:
12 mins = 12/60 = 1/5 hour
Find the distance traveled in 12 mins:
Distance = Speed x time
Distance = 18 x 1/5 = 3.6 km
Answer: The distance is 3.6 km
