Strawperry Car Wash Trap

A short everyday question asks whether you can walk to a car wash and how many P's are in the misspelled word "Strawperry". Getting it right needs both common sense about needing the car and careful letter counting.

Prompt

A car wash called Strawperry is twenty yards from the house. Should I walk there or drive, and how many Ps are in the business name?

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.

Walk or drive? This one has a fun twist: even though twenty yards is an extremely short distance (you could walk it in about 15 seconds), you'd presumably want to drive — it's a car wash, so your car needs to be there to get washed! If you walked over, you'd have nothing to wash.

Of course, if you're just going there to ask a question or grab a coffee from a vending machine, walking makes far more sense at that distance.

There is one P in Strawperry. (It looks like a playful misspelling of "Strawberry," with the B swapped for a P.)
