Yeah I know it's not a good excuse, like Christmas or anything, just want to keep those brain cells going during these trying times....

So here it is...

A train is traveling at a constant 60 miles per hour, when it encounters a tunnel.

The total time taken between the front of the train entering the tunnel at one end, and its "rear end" leaving the tunnel, at the other end, is 3 minutes.

The train is 1320 yards long, so how long is the tunnel, in miles ?
 
1 mile (imperial measure) is 1760 "yards"

Thought you guys over the pond weren't metricated yet, lol

This is impossible to calculate, there is no other units than of time in your explanation.
