Question

Kapil and Chandu start from Meerut and Lucknow respectively towards each other at the same time. They meet at Bareilly and then take 169 and 196 minutes respectively to reach their destinations. If the speed of Kapil is 42 km/h, then what is the speed of Chandu?  
1. 45 km/h
2. 39 km/h
3. 40 km/h
4. 38 km/h
5. 52 km/hr

Answer 1

Correct Answer - Option 2 : 39 km/h

Given:

Kapil's speed = 42 km/h

Kapil's time after meeting = 169 minutes

Chandu's time after meeting = 196 minutes

Formula used:

S₁/S₂ = √(T₂/T₁)

Calculation:

Let Chandu's speed be x km/h

So, 42/x = √(196/169)

⇒ 42/x = 14/13

⇒ x = 13 × 42 /14 = 39 km/h

∴ Chandu's speed is 39 km/h
