Trees grow from the top, not the bottom so house will not move up at all. So it will take 3 years.

Jay was planning to go to another country to visit relatives. The trip to the airport was long and boring, and since he didn't have a license, his mother had to drive him.

Jay was driven to the airport once from his house when he realized that he forgot his passport at home. His mother went back, got it, then brought it back. He then said he left his wallet at home. She went to get it, came back, and he had some more bad news. He left his cell phone at home. She went to go get it, but exactly halfway back, she found it in the glove compartment. She brought it back to him immediately, and he went off with his flight.

Assuming that the average car speed was 75 kph, the distance between the house and airport was exactly 50 km, and ignoring facts such as U-Turn time, time talking to son at the airport, time getting items, etc, how long did it take for Jay to leave, with the time starting when he left his house?

At a garden shop they're selling Magic Grass, a patch of sod that doubles in size every day. A man goes to buy some and figures that his garden is big enough that if he buys one patch, it will cover his garden in fourteen days, because each day it doubles in size. So he decides to speed up the process, and buys two patches of sod.

How many days will it now take for the Magic Grass to cover his garden?
