Two trains start at the same time from two stations and proceed towards each other at speeds of 90 km/h and 70 km/h, respectively. When they meet, it is found that one train has travelled 140 km more than the other, What is the distance (in km) between the two stations?
Answer & explanation
Correct answer: option 2
Ratio of Speed is 9 : 7
We know , Speed is directly proportional to Distance
Ratio of Distance = 9 : 7
According to question ,
( 9 - 7 )R = 140 km
2R = 140 km
1R = 70 km
So , Total Distance = ( 9 + 7 )R = 11R
= 16 × 70
= 1120 km
