The exam skills (3)
Timetables
- Find the right bus in the column (or row) it leaves from.
- Read down (or across) to the stop you want.
- Count the minutes between the two times, going through the hour.
Watch out: Subtracting times like ordinary numbers: 08:25 − 07:50 is not 75 minutes.
Distance charts
- Find the row of one town and the column of the other.
- The distance is where they meet.
- For a longer journey, find each leg and add them.
Watch out: Reading the wrong row because the chart is a triangle. Follow both names to where they meet.
Two-way tables
- Every row and column adds up to its total.
- Find a row or column with only one missing number.
- Total − the others = the missing number.
Watch out: Starting with a row that has two gaps.
