Question

suppose you are standing on the platform of a railway station watching the trains there is a train passing by without stopping it travels at 20 miles second and takes 6.9 second to pass you what is the length of the train​

Answer 1

Explanation:

1 mile = 1.6 approx km

then speed of train is 32 km / sec

then length of train is 32×6.9 = 220.9 km

length of train

Answer 2

Answer:

The length of the train is 138 m

Explanation:

Given :

• Train passing through the platform without stopping it travels at 20 miles second
• Train takes time to pass the platform is 6.9 second

To find: The length of the train

Formula used: Speed = Distance /time

Solution:

Given that train passing through the platform without stopping it travels at 20 miles second

Speed of train = 20 m/s

Train takes time to pass the platform is 6.9 second

Time = 6.9 sec

We know that,

Speed = Distance /time

Distance :

Distance is the actual length of the path travelled by the object.

Speed:

Speed is defined as the distance travelled in relation to the time required to travel that distance.

Time:

Time is referred to as the timespan during which everything occurs.

Speed = Distance /time

           = 20 × 6.9

          = 138 m

Length of the train is 138 m

Final answer:

The length of the train is 138 m
