Answer:
8.14 am
Step-by-step explanation:
7pm to 7.30 distance travelled by me = 40 km
150-40=110km distance
from 7.30 relative speed so both the persons speed act so we get
80+70=150 km/hr to travel 110 km how long does it take
150 60
110 x
(110*60)/150 = 6600/150= 44 minutes from 7.30 so both can cross each other by
7.30 +44 minutes =8.14 am
