It takes John 25 minutes to walk to the car park and 45 to drive to work. At what time should he get out of the house in order to get to work at 9:00 a.m.?

First, figure out how long it takes John to commute. 25 minutes walking plus 45 minutes driving. 25 + 45 = 70 minutes. Now turn the clock back 70 minutes from 9 a.m. 60 minutes makes it 8 a.m. and another 10 makes it 7:50.
