A train travels from Station A to Station B. If it travels at 80 km/h, it reaches 1 hour early. If it travels at 60 km/h, it reaches 1 hour late. What is the distance between the two stations?
Show answer & explanation
Correct answer: C
Explanation
Given:
Speed = 80 km/h → 1 hour early
Speed = 60 km/h → 1 hour late
Formula:
Time = Distance / Speed
Let distance = x km
x/60 − x/80 = 2
(4x − 3x) / 240 = 2
x/240 = 2
x = 480 km
