The research was carried out in Nottingham Trent University.
Mathematicians have created a formula to help prevent kids' tantrums on long car journeys.
Researchers at Nottingham Trent University, found the chances of a tantrum are reduced when a child is entertained, while a snack can help delay a meltdown by 15 minutes.
The study of responses by 2,000 parents, found the average child will take 70 minutes to throw a tantrum during a long car journey.
