if jams has to do work out every day for 20 minutes but only dose on to day for 30 mins and 15 mins how much minuts or hours should he do to get back all of the thing he has missed
If Jams is supposed to work out every day for 20 minutes but only worked out for 30 minutes on one day and 15 minutes on another day, he has missed a total of 20 + 20 - 30 + 20 - 15 = 35 minutes.
To make up for the missed time, Jams should work out for an additional 35 minutes.
