A train running at a speed 360 km/hr passes a platform with double length in 30 sec. Find the length of platform.

3 km

2 km

4 km

1 km

✅ Correct Option: 2

Speed $= 360$ km/hr $= 100$ m/sec. Let train length $= L$ , platform $= 2L$ . Distance covered $= L + 2L = 3L$ . Time $= 30$ sec. So $3L = 100 \times 30 = 3000$ m, giving $L = 1000$ m. Platform length $= 2L = 2000$ m $= 2$ km.
