Question

180 meter long train at the speed of 90 km/h will cross a 320 meters platform in ?​

Answer 1

Answer: The problem will be solved using the following formula -

Length of the Train + Length of the Platform (m) = Speed of the Train (m/s) * Time taken to cross the platform (s)

Here,

Length of Train = 180 m

Length of Platform = 320 m

Speed of Train = 90 km/h -> m/s = 90 * 5/18 = 25 m/s (To convert km/h to m/s, we multiply the value by 5/18)

Let the time time taken be train be x.

Using the formula stated above, we get -

180 + 320 = 25 * x

500 = 25 * x

x = 500/25 = 20

Hence, the time taken by the train is 20 seconds.

Answer 2

Answer:

Step-by-step explanation:

i will take the back part of the train as a point

so the initisl distance=320+180=500m(for the back part of the train)

90km/h=25m/s

so time=distance/speed=500/25=20s

hope this helps you

thank you
