John leaves his house one morning to go to the store which is 16 middles dude my north. Suzie, his wife, leaves the house and drives to work, which is directly east of the store.John needs to drop off lunch for suzie because she forgot to pack a lunch today. If suzie has a 20 mile drive to work from home, how far must John drive to store to deliver her lunch?
