The problem can be solved as follows – Formula: As the answers are given in metres, we need to first convert the speed of the train from km/hr to m/s. The formula to convert km/hr to m/s is, A km/hr = (A x 5/18) m/s Here, A = 60 km/hr. 60 km/hr = [60 x 5/18] m/s ==> 50/3 m/s. So, the train is traveling at a speed of 50/3 m/s. We already know that distance = speed x time The distance between the train and the pole = 50/3 x 9 = 150 metres. Here, distance can be considered as the length of the train. Hence, the length of the train is 15 metres. 2 Share Share Share on Facebook Share on Twitter Share on WhatsApp Share on LinkedIn Shivateja Expert 2021-01-25T09:47:43+05:30Added an answer on January 25, 2021 at 9:47 am 60 km/hr = 60 x 5/18 m/s = 50/3 m/s The train is set to cross the pole in 9 seconds.

The length of the train is 150 metres. The problem can be solved as follows –

Formula:As the answers are given in metres, we need to first convert the speed of the train from km/hr to m/s. The formula to convert km/hr to m/s is,

A km/hr = (A x 5/18) m/s

Here, A = 60 km/hr.

60 km/hr = [60 x 5/18] m/s

==> 50/3 m/s.

So, the train is traveling at a speed of 50/3 m/s.

We already know that distance = speed x time

The distance between the train and the pole = 50/3 x 9 = 150 metres. Here, distance can be considered as the length of the train.

60 km/hr = 60 x 5/18 m/s = 50/3 m/s

The train is set to cross the pole in 9 seconds. So, length of the train = speed x time

==> 50/3 x 9

==>

.150 metres is the length150 metres
