Question

a 190m long train is running at a speed of 38 km/h how much time it will take to cross a pole​

Answer 1

the answer is 8.49 second

Step-by-step explanation:

Let’s start

its simple see

length of train = 190m

speed of train = 38 km/hr = 10.60 m/s

(38*5/18) m/sec = 10.60 m/s

so now we have to find the time to cross 190 m of length

10.60m → 1 sec

1 m →1/10.60 sec

190m → 1/10.60*190 sec

=8.49sec

Answer 2

Step-by-step explanation:

Let’s start

the answer is 7.2 second

its simple see

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
