Solution
1 inch = 120 km
Distance between A and B = `4 1/6`
Distance between A and C = `3 1/3`
∴ Distance between B and C = `4 1/6 + 3 1/3` inches
= `25/6 + 10/3`
= `25/6 + 20/6`
= `(25 + 20)/6`
= `45/6` inches
1 inch = 120 km
∴ `45/6` inches = `45/6 xx 120 "km"` = 900 km
Distance between B and C = 900 km
