1. Utilize standard measures of rate, such as calculating: • hourly wages • currency exchange rates • rates of flow • fuel efficiency. 2. Use additional measures of rate, including calculations for: • pressure • density • population density. The necessary formulas will be provided in the question. 3. Address problems related to average speed, requiring knowledge of the speed/distance/time formula. For example, if a cyclist covers 45 km in 3 hours and 45 minutes, determine their average speed. Notation examples include m/s (metres per second) and g/cm³ (grams per cubic centimetre).
