Correct Answer - Option 1 : 1: 30 P.M.
Given:
Distance between Delhi and Chandigarh = 300 km
The train starts at 11 : 00 A.M.
Formula used:
Speed : distance/time
Calculation:
Speed of train : 300/3
= 100 km/h
Speed of car = 300/6
= 50 km/h
Distance travelled by train from 11: 00 A.M. to 12 : 30 A.M. is 150 km
Remaining distance = 300 – 150 = 150 km
Relative speed of train and car = (100 + 50)km/h
= 150 km/h
Time : 150/150
= 1 hour
Hence, the train and car meet at 1 : 30 P.M.
