Question

If A and B run at 6 km/hr and 12 km/hr on a circular track 6 km long, when will they meet for the first time if they
are running in opposite direction​

Answer 1

in 1/3 hr they will meet

Answer 2

Answer:

For A concern speed is 6*5/18=1.6

For B concern speed is 12*5/18=3.3

When they are opposite direction formula is L/(a+b)

So 6km is 6000meters

6000/(3.3+1.6)=1200

So answer is 1.2km
