A motorist goes for a drive, keeping the reading on the speedometer at a constant value of 40km/h. The speedometer is assumes to be accurate to +/- 2km/h. At the end of the day he wants to know how far he has travelled, but unfortunately, he forgot to look at the distance indicator when he set out. He thinks that he drove for four hours, give or take a quartee of an hour. Estimate how far he travelled and assign an error to your result.
