It takes a lot of snow ofr the federal government in Washington D.C. to shut down, but even they experienced a two-hour delay last Friday. This is to allow people to take it slow in thier way to work. A commute to work that usually takes someone 24 minutes traveling at an average speed of 37.5 mph, but that was not possible that day. On this snowy day, tha average rate of speed this peson could travel was only 15 mph due to conditions. How many minutes did the commute to work take?

I don't understand how to do this. Please help.

thank you!

Since 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.

Let'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.

At 15 miles per hour, you cover 15 miles in one hour.
