Tim's trip

Tim left at 6:00. We had to figure out how long Tim had at his grandmas house.  He wanted to be back home to his house to watch his favourite tv show by 7:00pm.   On the way to his grandma's house there are hills so he can go 14 kph .  But on the way back he can go 21 kph.So we figured out that he can spend 10 minutes with his grandma and he will have 50 minutes to get there and back .by Rana and Kirsten
