The key idea
Here movement is along one grid row, not diagonally.
grid distance = steps × distance per step
Worked examples
On one map-grid row, move from column 7 to column 12. Each step is 18 km. How many km is the journey?
(12 − 7) × 18 = 90
90 km
On one map-grid row, move from column 8 to column 17. Each step is 20 km. How many km is the journey?
(17 − 8) × 20 = 180
180 km
