Time, Speed & Distance

Easy

The speed of a 90 meter long train is 45 km/h. A man is standing right next to the railway line. How much time will the train take to cross the speed increases by 20%?

4.8 second

5.0 second

6.0 second

7.2 second

✅ Correct Option: 3

Increased speed $= 45 \times 1.2 = 54$ km/h $= 54 \times \frac{5}{18} = 15$ m/s.

To cross a stationary man the train covers only its own length, $90$ m.

Time $= \frac{90}{15} = 6$ seconds.

Note: The NTA sentence omits the object being crossed. We have read it as the time to cross the man standing beside the track after the speed rises by 20%.
