You asked this already:
1 mile / 15 miles/hour = 1/15 hour
1/15 hour * 60 minutes = 4 minutes
It will take 4 minutes to be fully in the tunnel.
It will take another 4 minutes to be fully out of the tunnel.
Total time to be through the tunnel: 8 minutes.
Alternatively, do this in one step as 2 miles / 15 miles/hour * 60 minutes/hour = 8 minutes

The basic formula for this is: distance = rate x time or d = r x t.
In this case we know the distance the train travels from the time the first car enters the tunnel until the last car leaves the tunnel is 2 miles. The rate is 15 mph. We need to find the time or t.
Since d = r x t, then d/r = t. Dividing 2 miles by 15 mph we get 2/15 hour, which is equal to 8 minutes.

15 miles per hour rate of travel- divide 15 into 60 (number of mins per hour) the answer is the time it takes to travel through the tunnel.

60 miles in step with hour is one mile in step with minute (60 miles in 60 minutes) So the engine or front of the prepare will take one minute and since the front exists the rear will enter and take yet another minute to sparkling tunnel. So 2 minutes entire.

8 Min's!!
its traveling at 0.25 miles a Minute, considering that the tunnel and train together is 2 miles long so 2 divide by 0.25 that would be 8. Thanks Nice one
