The speed of a boat in still water is 15 km/h and the speed of the current is 3 km/h. How much distance (in km) can be covered going downstream in 12 minutes?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e 3.6.
Downstream speed = Boat speed + Current speed = 15 + 3 = 18 km/h
Distance = Speed × Time = 18 × 1/5 = 3.6 km
