I got a packet over the weekend with all trigonometry questions but there's one algebra problem that I'm stuck on, although it's probably really simple. It's referred to a previous problem asking what the angle of elevation and vertical rise but that probably doesn't matter for this question.

A 2 mile train is traveling at 10 MPH. To the nearest minute, how long will it take the train to completely pass through a tunnel that is exactly one mile long?
