Correct Answer: 15
Correct Answer: 120
Explanation:
Distance covered by A till 6pm = 60 km
Distance covered by A till 7 pm = 120 km
Time taken by B to catch A = 60/(80-60 ) = 3 hrs
So A and B will meet at 6pm + 3 hrs = 9pm
Since we know that all three met at the same time
The time taken by C to cover 120 km
difference will be = 9pm ?7pm = 2hrs
Therefore,(x ?60 )*2 = 120x = 120 km/hr
