Detailed Solution
Download Solution PDFGiven:-
An 1800 m long train is running at the speed of 30 km/hr.
The train passes a signal pole near the railway line.
Formula used:-
1 km = 1000 m,
1 hr = 3,600 seconds (s)
Time = Distance/Speed
Calculation:-
Length of train = Distance covered in passing the pole = 1800 m
Speed of train = 30 km/hr
⇒ Speed of train = (30 × 1000)/(1 × 3,600) m/s
⇒ Speed of train = 25/3 m/s
Time = Distance covered by train in passing the pole/Speed of train
⇒ 1800/(25/3) seconds
⇒ 216 seconds
∴ The required answer is 216.
