Converting km to miles

Ashmansworthy class have using maps to calculate distances between places in North Devon. Once the distance on the map had been calculated in cm, it was converted to km by dividing by two (2cm = 1km on a 1:50,000 map). Then we used a conversion chart to work out the distance in miles. Some children knew that 1km = 0.6 miles so they multiplied the km by 0.6 to calculate their answer.
