Question

Two trains start at the same time from Stations A and B respectively and travel towards each other at a speed of 60 km/h and 40 km/h, respectively. At the time they meet, the faster train has travelled 60 km more than the slower train. What is the distance between the two stations?

• A. 300 km
• B. 450 km
• C. 360 km
• D. 420 km

Answer 1

Answer:

A. 300 km

train A speed = 60kmph

train B speed = 40kmph

total time taken = t

train A faster than 60 km mor than train B

distance traveled by train A = 60t

distance traveled by train B = 40t

$60t-40t=60$

$20t=60$

$t=3hrs$

distance $D=60t+40t$

$D=60(3)+40(3)$

$D=180+120=300 km$
