A 160 m long train crosses a 160 m long platform in 16 seconds. Then the speed of the train is:
Show Hint
To convert m/s to km/hr, multiply by \( \frac{18}{5} \).

- 55 km/hr
- 60 km/hr
- 72 km/hr
- 75 km/hr
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
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.
\[
20 \times \frac{18}{5} = 72 \text{ km/hr}
\]
