1) Bill gates makes approximately $4 billion a year. On average, how much does he make per minute? 2) Imagine that you are driving your car in Canada. As you are driving along, you notice that the speed limit signs have numbers like 120 (on the highway) and 50 (in the city). As you start to speed up, you realize that the signs are in km/hour.
