A train starts from Delhi at 11 : 00 A.M. and reaches Chandigarh at 2: 00 p.m. and a car start to move from Chandigarh at 12: 30 P.M. and reaches Delhi at 6 : 30 P.M. If the distance between Delhi and Chandigarh is 300 km, then at what time the train and car meet each other? Correct Answer 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.

There is only one rail track between stations A and B on a railway line. One hour after the northbound superfast train N leaves station A for station B, the southbound passenger train S reaches station A from station B. The speed of superfast train is twice that of express train E, while the speed of passenger train S is half of that of train E. On some one day train N leaves from station A to station B 20 minutes late than its usual schedule. Both Train N and Train S have increased their speed to maintain the schedule as per the table. If the superfast train doubles its speed, then what should be the ratio (approximately) of the speed of the passenger train to the speed of the superfast train so that the passenger train reaches the station on that day at the exact scheduled time.
