Question

A train crossed a pole in 8 seconds at the passesed of 63 km/hour find the length of train

Answer 1

Answer:8.4 km

Step-by-step explanation:

Speed=Distance/Time

Distance=Speed×Time

We have:

Distance=?

Speed=63km/h

Time=8s Or 2/15h

Distance=63×2/15

=8.4km

Answer 2

$\bf{\huge{\underline{\boxed{\sf\orange{Answer:140\:m}}}}}$

Given :

• Train crossed a pole  in 8 seconds at the speed of 63 km/hr

To Find :

• Length of the train.

$\huge\underline\green{Solution:}$

→ Distance covered = length of the train.

∵ Speed = $\dfrac{Distance}{Time}$

               $=63\times\dfrac{5}{18}$

              $= 17.5 m/s$

→ Time = 8 seconds.

→ Length of the train ( Distance covered ) = Speed × Time

= 17.5 × 8

= 140 m

Answer : Length of the train is 140 m
