A railway train 100 meters long is running at speed of 30 km/h in what time it pass a bridge 80 meters long?
A railway train 100 meters long is running at speed of 30 km/h in what time it pass a bridge 80 meters long?
Explanation
To find the time taken, first, calculate the total distance the train needs to cover:Total distance = Length of train + Length of bridge
= 100 m + 80 m
= 180 m
Convert the speed from km/h to m/s:
30 km/h = 30 × (1000 m / 3600 s)
= 30 × 5/18
= 8.33 m/s
Time taken = Distance / Speed
= 180 m / 8.33 m/s
= 21.6 seconds
