Question 970656: If Jim’s work shift starts at 8:45 a.m. and Jim arrives to work at 9:13 a.m., how many minutes late was Jim? Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! From 8:45 to 9 is 15 minutes
From 9 to 9:13 is 13 minutes
Add the two
He was 28 minutes late.
Work to hours with time problems like this. Don't try to subtract.
You can go backward, but I like going forward.
