Question

A train 180 m long,is running at a speed of 60 km/h. How long will it take to cross a pole​

Answer 1

Answer:

the answer is 7.2 second

Step-by-step explanation:

length of train = 180m

speed of train = 90 km/hr = 25 m/s

(90*5/18) m/sec = 25 m/s

so now we have to find the time to cross 180 m of length

25 m → 1 sec

1 m →1/25 sec

180m → 1/25*180 sec

=7.2 sec

Answer 2

Answer:

11.25 is the ans

Step-by-step explanation:

length of train = 180m

speed of train = 60 km/hr = 16 m/s

(60*5/18) m/sec = 16 m/s

so now we have to find the time to cross 180 m of length

16 m → 1 sec

1 m →1/16 sec

180m → 1/16*180 sec

=11.25 sec
