Question

A train with a length of 700m moving at a speed of 80Kmph passes through a tunnel in 3 minutes, what is the length of the tunnel ?​

Answer 1

Step-by-step explanation:

formula =

time (sec) = leng of train +Leng of tunnel /spped ×18/5

substituting values we get

180 = 700 +x /80× 18/5

180×80 = 700 +x ×18/5

14400×5 =700+x ×18

72000=700+x×18

72000/18=700+x

4000=700+x

x=4000-700

x=3300
