Asked by Amaani

David drove a distance (d) of 187 km, correct to 3 significant figures. He used 28 litres of petrol (p), correct to 2 significant figures. The petrol consumption (c) of a car, in km per litre, is given by the formula C= d р By considering bounds, wor?

Well the formula to be used here is C = d / p so 187 / 28 = 6.6785 The answer will be C = 6.7 as we use the accuracy of 2 significant figures (the lowest number of significant numbers in our given variables is used for our answers)
