Two trains each 500 metres long, are running in opposite directions on
parallel tracks. If their speeds are 50 km/hr and 40 km/hr respectively, the
time taken by the slower train to pass the driver of the faster one is _______seconds
🎥 Video solution / Text Solution of this question is given below:
Speed of faster train $= 50$ km/h $= 13.89$ m/s
Speed of slower train $= 40$ km/h $= 11.11$ m/s
Relative speed (opposite directions) $= 13.89 + 11.11 = 25$ m/s
Distance to be covered $= 500$ m
Time $= \dfrac{500}{25} = 20$ seconds
Answer: $\boxed{20\text{ seconds}}$ ✅
