# How Much Far Both from Each Other? If

If A and B are running in opposite direction at a speed of 9 km/hr and 6 km/hr respectively, then what will be the difference between them after 2 hours?

- 30 km
- 13 km
- 42 km
- 21 km

**Answer: (1) 30 km**

**Explanation:-
**The speed of A = 9 km/hr

The distance covered by A in 2 hrs = 9 x 2 = 18 km

The speed of B = 6 km/hr

Then, the distance covered by B in 2 hrs = 6 x 2 = 12 km

They are running in the opposite direction,

Then, the distance between A and B = 18 + 12 = 30 km.

Hence, the answer is (1) 30 km.
