You should probably drive, but it depends on why you are going there! Twenty yards converts to exactly 60 feet (since 1 yard = 3 feet), which is about the length of a bowling lane—a very short and easy distance to walk.

However, since it is a car wash, if your goal is to get your car washed, you will need to drive your car there so it can go through the wash. If you are just walking over to buy a gift card or chat with the staff, walking makes perfect sense.

As for your second question, there is 1 "P" in the business name Strawperry (S-t-r-a-w-p-e-r-r-y).

Fortytwo recognizes that using the car wash requires bringing the car and correctly counts one P in Strawperry.

Here are the answers to your questions:

1. Should you walk or drive?

  • If you are going there to get your car washed: You should drive, because it is very difficult to wash a car that is still parked in your driveway!
  • If you are just going there for any other reason (like working a shift or talking to someone): You should definitely walk. Twenty yards is only 60 feet (about 18 meters), which is less than a 10-second walk. Driving that short of a distance is unnecessary and doesn't even give your car's engine time to warm up.

2. How many "P"s are in the business name?
There is exactly one "P" (lowercase "p") in the name Strawperry (S-t-r-a-w-p-e-r-r-y).

Gemini 3.5 Flash distinguishes between getting the car washed and merely visiting the nearby business, and reports exactly one P in Strawperry.
