SSC CHSL - 16th October 2020 - Shift 2 • Quantitative Aptitude • Q52

Two trains start at same time from stations A and B, 1800 km apart, and proceed towards each other at an average speed of 44 km/h and 46 km/h, respectively. Where will the trains meet?

Show answer & explanation

Correct answer: D

Explanation

The correct answer is Option 4 i.e 880 km from station A.

Understanding/Application

Distance between two stations A and B = 1800 km

Average speed of train that starts from station A = 44 km/h

The average speed of the train that starts from station B = 46 km/h

Both trains are moving in the opposite direction -

Thus, the relative speed will be = (44 + 46) = 90 km/h

Time = distance /speed

Time after which they meet = 1800/90 = 20 hours

Distance travelled by train that started from station A in 20 hours = (44 × 20) = 880 km

Distance travelled by train that started from station B in 20 hours = (46 × 20) = 920 km

Meeting point from station A = 880 km
