**Matt**, Thursday, February 7, 2008 at 4:28pmSince it takes 25 minutes at 37.5 MPH, we know that in 60 minutes, they would go 37.5 miles. We need to know how long to commute is. 25/60 = 5/12, so you multiply 37.5 by 5/12. The answer is 15.625, this is how long the commute is. 15 MPH is 4 minutes per mile, so you multiply 4 by 15.625, giving you 62.5

62.5 minutes.

**Ms. Sue**, Thursday, February 7, 2008 at 4:34pmLet's start with changing 24 minutes to a fraction of an hour. 24/60 = 0.4

At an average speed of 37.5, then it normally takes a person 37.5 * 0.4 = 15 miles.

On a snowy day at 15 mph, it would take an hour to drive 15 miles.
