A math professor has reportedly discovered an equation that will tell parents how long it will take for the kids to say “are we there yet?”
The equation created by Dr. Dwight Barkley of the University of Warwick uses a multitude of factors to mathematically predict the exact moment.
T = (1 + a)/(k^2) + r
- T = The time for the child to ask
- a = The number of activities to do
- k = The number of kids
- r = How long it took to get ready
If we take this equation in minutes and say it took us 30 minutes to get ready, we have 2 kids, and we’ve given them each three travel games, we get:
T = (1 + 3)/(2^2) + 30 = (1)/(1) + 30 = Exactly 31 minutes, or exactly one minute after you get into the car.
Let’s try 30 minutes to get ready, 3 kids, and 20 games.
T = (1 + 20)/(5^2) + 30 = (21)/(9) + 30 = 32.3 minutes, or exactly 2.3 minutes after you get into the car.
Ouch! Looks pretty hopeless to me, either way. I think we need an equation that shows what size car you will need, and therefore how much gas you will expend on trips, in order to hold all the kids activities (a) in order to keep them quiet for at least 10 minutes.
