Question 453323: Hi, I just started an Algebra class and I'm no sure how to solve this problem using Algebra. Any and all help is appreciate tremendously!!! Thank you Thank you!!
In 2005, the average commuting time to work in New York was 31.2 min. The average commuting time in North Dakota was 14.9 min shorter. How long was the average commute in North Dakota?

You can put this solution on YOUR website!
Let Y and D be the commuting times for New York and North Dakota. Then,

D = Y - 14.9

Replace Y with 31.2 since we know the commuting time for New York.

D = 31.2 - 14.9 - 16.3 min
