Answer 2

 

Given :-

• Length of the train is 200m  

• Speed of the train is 15m/s  

• Length of the bridge is 355m  

To Find :-

• Time the train will take to cover the bridge.

Solution :-

~Here, we’re given the length, speed of train, length of the bridge and we need to find the time the train will take cross that bridge. The total distance covered by the train will be the sum of the length of train and the length of the bridge , we’re given the speed so we can find the time taken by putting the values in the formula of finding the total time taken.  

____________

As we know that ,  

$\boxed{\sf{ \maltese \;\;Total\;time\;taken = \dfrac{Total\;distance}{speed}}}$  

Finding the total distance covered :-  

$\sf \implies Length\;of\;train+length\;of\;bridge$

$\sf \implies 200\;m + 355\;m$  

$\boxed{\bf{ \;\; 555\;m}}$

Finding the time taken :-

$\sf \implies \dfrac{ distance}{speed}$

$\sf \implies \dfrac{555}{15}$

$\boxed{\bf{ \bigstar \;\; 37\;seconds }}$

____________

Hence,  

• The time taken by the train will be 37 seconds
