Difficulty: 3/5

You just woke up from sleep and looked at the time. It’s 8:30 now and you need to be at grandma’s at 8:47. That gives you 17 minutes. You are taking three other family members with you, but there’s a catch. Your sportscar can only hold two people at a time, so you’ll have to take multiple trips, and some of your family members take longer to drive than others. You can drive your car fast and it takes you a minute to get to grandma’s. Your sister just learned to drive but is still pretty good at driving and takes two minutes to get to grandma’s. Your father is getting old and takes five minutes, and your mother is extremely cautious and takes ten whole minutes. Also, even if you can drive to grandma’s in one minute, if you have a passenger, for example, your mom, then it will still take you ten minutes to get to grandma’s because your mom slows you down. Finally, your grandma is a war veteran and hates when people are not punctual, so if you are even a minute late, she will beat you with her cane. 

Is it possible to make it to grandma’s in time or will you get THE CANE!!!

Clues:

• It takes you 1 minute to get to grandma’s, your sister takes two minutes, your dad takes five minutes, and your mom takes ten.
• Your car can only hold two people at a time.
• You have 17 minutes in total.
• You will have to take multiple trips. Getting back from grandma’s takes the same amount of time to get to grandma’s. Example: It takes you one minute to get to grandma’s, therefore, it takes you one minute to get back from grandma’s.
• Even if you can drive fast, it takes you the same amount of time to get to grandma’s as the slowest person in the car. Example: You and your sister would take two minutes because your sister takes two minutes. It doesn’t matter if you can drive faster.
• There must always be someone driving the car when moving. You can’t launch your car back to your house.

Solution: DO NOT READ UNLESS SOLVED

For you, it probably seems that no matter how fast you go, the clock ticks faster. It seems as if you’ll always be at least a minute late, no matter what, but it is still possible. The main trick is to keep the slowest people together, minimizing the time wasted by them, but at the same time, you still need a fast way to get back. Here are the steps and times:

• You and your sister go to grandma’s first, taking two minutes. 8:32
• You drive back to your house, taking one minute. 8:33
• Your mom and dad drive to grandma’s, taking ten whole minutes. 8:43
• Your sister drives back to get you at your house, taking two minutes. 8:45
• You and your sister drive back to grandma’s, taking two minutes. 8:47

You just barely beat the clock, and thankfully, your grandma beating you. Maybe next time you’ll set an alarm clock!
