|---|---|---|
| 48 | M1 | for taking a suitable reading from the graph that could be used to convert, eg 25 km = 15.5 miles or 17 miles = 27.2 km |
| M1 | ft, for a complete method, eg \(\text{``}15.5\text{''} \times 2 + 17\) or \((\text{``}27.2\text{''} + 50) \div 1.6\) | |
| A1 | for an answer in the range 47 – 49.5 |
Additional guidance
Allow a tolerance of one small square for the reading eg
10 km = 6 – 6.5 miles
20 km = 12.25 – 12.75 miles
25 km = 15.25 – 15.75 miles
30 km = 18.5 – 19 miles
for miles to km allow
1 mile = 1.6 km
17 miles = 27 – 28 km
For ft, allow use of their stated conversions but they must be conversions that could have come from graph
