(A) 7 : 52 AM
(B) 8 : 25 AM
(C) 6 : 52 AM
(D) 9 : 25 AM
Correct Option is: C
Time taken by John = 8 h
Time taken by Michael = 7 h
For your convenience take the product of times taken by both as a distance.
Then the distance = 56km
Since, John covers half of the distance in 2 hours(i.e at 5 am)
Now, the rest half (i.e 28 km) will be coverd by both Michael and John
Time taken by them = 28/15 = 1 hr 52 min
Thus , they will cross each other at 6 : 52 AM
