Answer 1

Answer:

350 m for no 6

Step-by-step explanation:

We Know that Distance=Speed*Time

we are provided with Speed and Time to taken to cross the bridge  so,

Given,

Speed of train In bridge=36km/h = 10m/s as time is in second the speed will also be in second

Time taken to cross the bridge=55 Sec

Now using formula we have

Distance=Speed * time

              =10*55=550

so the length of train and bridge is 550 now removing trains length that is 200 m we will get our answer

so,length=550-200

               350 m
