A statistician has calculated the "exact formula" for predicting the chances - and timing - of children throwing a tantrum in the backseat of a car during a long journey.
According to Dr James Hind, from Nottingham Trent University, T = 70 + 0.5E + 15F - 10S is the code parents can use to crack the probability of their offspring's backseat breakdowns.
Dr Hind's research, which was developed alongside LV= Britannia Rescue and based on responses from 2,000 parents, found that the time (T) the average child will typically take to throw a tantrum during a long car journey is 70 minutes.
