Question

A 270 metre long goods train is running at 40.5km/h . How much time it will take to cross a tree

Answer 1

Given :-

• Length of Train = 270m .
• Speed of Train = 40.5km/h.

To Find :-

• How much Time it will take to cross a tree ?

Concept & Formula used :-

• When Tree cross a Tree , distance Train cover is Equal to Length of Train .
• To convert speed into m/s , multiply it by (5/18).
• Time = (Distance/Speed).

Solution :-

→ Distance covered by Train = Length of Train = 270m.

→ Speed of Train = 40.5km/h = 40.5 * (5/18) = 11.25m/s.

So,

→ Time taken By Train to cross a Tree = (D / S) = (270/11.25) = 24 Seconds. (Ans.)

Hence, The Train takes 24 seconds to cross a Tree.

Answer 2

$\huge\tt{GIVEN:}$

• A 270 metre long goods train is running at 40.5km/h

_____________________________

$\huge\tt{TO~FIND:}$

• Time taken by it to cross the tree

____________________________

$\huge\tt{SOLUTION:}$

We can say that The distance covered by the train would be that of what it's length is

Then ,

↪Distance = 270 m

↪Speed of the train = 40.5 km/hr or 11.25 m/sec

We know that, Time = Distance/Time

↪Time taken by the train to cross the tree = (270/11.25) = 24 seconds

$\tt{Time~Taken~By~The~Train~To~Cross~}$

$\tt{~The~Tree~=~24~seconds}$
