1. The speed of a boat in still water in 15 km/hr and the rate of current is 3 km/hr. The distance traveled downstream in 12 minutes is
- A. 1.2 km
- B. 1.2 km
- C. 1.2 km
- D. 1.2 km
Answer: Option B
Explanation:
Speed downstream
= (15 + 3) kmph
= 18 kmph
Distance travelled
= (18 × 12/60) km
= 3.6 km
= (15 + 3) kmph
= 18 kmph
Distance travelled
= (18 × 12/60) km
= 3.6 km
