Answer:

5 min

Step-by-step explanation:

time taken=distance required to travel/speed of train

total distance train have to cover to just left the tunnel is (lenght of tunnel+length of train) =2km+250m

=2250m

speed of train is 27km/hr

multiply 5/18 to convert in m/s

i.e, (5/18)×27=7.5m/s

now time taken =2250m/(7.5m/s)

=300s

and,300s =5min
