Answer this question:John plays a game for 4 hours a day every day for 2 weeks. After all that time, he is only 40% done. He increased his playtime to 7 hours a day. How long until he finishes the game?
There are 7 * 2 = 14 days in two weeks. So he played 14 * 4 = 56 hours. That means the total length of the game is 56 / .4 = 140 hours. So he has 140 - 56 = 84 hours to beat the game. So it will take him 84 / 7 = 12 days to beat the game.
The answer is 12.

Answer this question:The pizza delivery person has 12 pizzas to deliver. If two of the stops are for orders of two pizzas and the rest are for single pizzas, how many minutes per stop does the delivery person need to average to deliver all of the pizzas in 40 minutes?
If two pizzas will be delivered at two of the stops, the total number of stops will be 12 - 2 = 10 stops. If there are 10 stops in 40 minutes, then the delivery person needs to average 40 / 10 = 4 minutes per stop.
The answer is 4.

Answer this question:A banana tree has 100 bananas left after Raj cut some bananas from it. If Raj has eaten 70 bananas and has twice as many remaining in his basket, how many bananas were on the tree initially?
If Raj has eaten 70 bananas in the basket, he has 2 * 70 = 140 bananas. The total number of bananas that Raj cut from the tree is 140 + 70 = 210. On the tree initially were 100 + 210 = 310 bananas.
The answer is 310.
