### Rates of Change GCSE Maths; this section explains how to calculate rates of changes and repetitive rates of change using graphs for higher GCSE Maths

The exchange rate was £1 = €1.68 (a) Change £325 into euros (€). € .. (2) When she came home she changed €117 into pounds. The new exchange rate was £1 = €1.50 (b) Change €117 into pounds. £ .. (2) (4 marks) The gradient of the line represent the rate of change. The formula is therefore the change in the y axis divided by the change in the x axis. In this example that equals 10 ÷ 40 = 0.25. This represents a charge of 25p per minute and shows a constant proportion. Average Rate of Change - Corbettmaths - Duration: 6:16. corbettmaths 8,337 views GCSE Maths revision tutorial video.
