Answer 2

They will meet after 20 minutes for the first time if running in opposite direction.

Step-by-step explanation:

Since we have given that

Speed at which A runs = 6 km/hr

Speed at which B runs = 12 km/hr

It runs in opposite direction,

Relative speed of A and B = 6+12 = 18 km/hr

Distance = 6 km

So, Time would be

$\dfrac{Distance}{Speed}=\dfrac{6}{18}=\dfrac{1}{3}\times 60=20\ minutes$

Hence, they will meet after 20 minutes for the first time if running in opposite direction.
