Question

Bombay Express left Delhi for Bombay at $14.30$ hrs travelling at a speed of $60$ kmph and Rajdhani Express left Delhi for Bombay on the same day at $16.30$ hrs travelling at a speed of $80$ kmph. How far away form Delhi will the two trains meet ?

• A. $120$ km
• B. $360$ km
• C. $480$ km
• D. $500$ km

Answer 1

The correct option is C $480$ km

Suppose they meet $x$ hours after $14.30$ hrs.

Then,

$60x=80(x-2)$

$60x=80x-160$

$-20x=-160$

$x=8$

$\therefore$ Required distance $=(60\times 8)km=480km$.
