Question

Paschim Express left Delhi for Mumbai at $14.30$ hrs travelling at a speed of $60$ kmph and August Kranti Express left Delhi for Mumbai in the same day at $16.30$ hrs travelling at a speed of $80$ kmph. How far away from Delhi will the two trains meet (excluding stoppages)?

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

Answer 1

The correct option is C $480$ km

Suppose the two trains meet $x$ km from Delhi.
Then, $\frac{x}{60}-\frac{x}{80}=2$
$\Rightarrow \frac{x}{240}=2$
$\therefore x=480$ km
