Suppose I wanted to calculate the speed of a car from measured values of distance and time. If I measured 10 meters with an uncertainty of 20% and the time it took to travel that distance as 1 second with an uncertainty of 20%, what is the LARGEST speed may calculation should include in the uncertainty?
