A train travels = 4 hours
B train travels = 3.5 hours
distance of point a and B is lcm of time
4 , 3.5 = ( 28 km)
A speed = 28/4 = 7km/hr
B speed = 56/7 = 8 km/hr
7 : 00 to 8 : 00 Tarin a runes
in one hours cover distance 7 km
distance remains = 28 - 7 = 21 km
A + B distance cover in one hours
= 7 + 8 = 15 km
together complete distance 21 to reach together at reach point
21/15 = 1.4 hours
1.4 × 60 = 84 minutes
8 : 00 + 84 minutes
9 : 24 am
