Jonas is a marathon runner. He runs the first part of a marathon in 22 minutes. Then he runs at a pace of 11 miles per hour, which means it takes him 5.5 minutes to complete each mile.

Y = total time
X =  number of miles after the first part of the race

when X=0 (just after first part, Y = 22 minutes
Then he takes 5.5 minutes to cover each mile. So total time becomes

Y = 22 + 5.5X 
where X is in miles and Y is in minutes.
