Question

A 160 m long train crosses a 160 m long platform in 16 seconds. Then the speed of the train is:

• A. 55 km/hr
• B. 60 km/hr
• C. 72 km/hr
• D. 75 km/hr

Hint:

To convert m/s to km/hr, multiply by \( \frac{18}{5} \).

Answer 1

The Correct Option is C

Step 1: Total distance covered = length of train + length of platform. \[ \text{Total distance} = 160 + 160 = 320 \text{ meters} \] Step 2: Time taken = 16 seconds. Use speed = distance/time. \[ \text{Speed} = \frac{320}{16} = 20 \text{ m/s} \] Step 3: Convert m/s to km/hr. \[ 20 \times \frac{18}{5} = 72 \text{ km/hr} \]
