3 Draw a line graph. Choose between: ● ●
● ●
a line graph converting Japanese Yen to Euros,
Remember to choose the scale of the graph carefully. Work out the lowest and greatest values first.
a line graph converting Japanese Yen to US Dollars, or a line graph converting Euros to US Dollars two currencies of your choice (you will need to look this up on the Internet!)
4 This line graph shows the distance travelled when a vehicle is travelling at 30 kilometres per hour, compared to 40 kilometres per hour.

Use either calculations or the line graph to solve these questions and then check with the other method. (a) How far will a car have travelled in 2 hours if it is travelling at 40 km/h? (b) How far will a car have travelled in 2 hours if it is travelling at 30 km/h? (c) How much further has a car travelled after 1 hours if it is travelling at 40 km/h rather than 30 km/h? (d) How many kilometres will a car have travelled after 4 hours if it is travelling a 30mph? (e) How many kilometres will a car have travelled after 10 hours if it is travelling 40 km/h?
