... How many minutes did he run for in 3 miles and 4 miles.  I think your question is incomplete.

Ok, well lets see here.  It's a linear function, which means that it's moving in a steady line.  This means that the slope stays the same.  Since we know that the line is increasing at a steady pace we can just subtract 28 from 38 equal to 38-28=10    In other words, 1 mile takes 8 minutes.  2 miles takes 18 minutes.  3miles takes 28 minutes.  4 miles takes 38 minutes, and finally, 5 miles takes 48 minutes.  Does that makes sense?
