Question 21 • FL-1205040-M/J Grade 7 Mathematics B -GF

On a map, Melbourne, Australia, is 22 centimeters from Sydney, Australia. The actual distance is 880 kilometers. If Canberra, Australia, is 286 kilometers from Sydney, how far apart will they appear on the map, to the nearest centimeter?

Answer
A
3 centimeters
B
7 centimeters
C
13 centimeters
D
68 centimeters

Explanation

The map scale is 22 centimeters for 880 kilometers, or 22 ÷ 880 = 0.025 centimeter per kilometer. For 286 kilometers, the map distance is 286 × 0.025 = 7.15 centimeters, which rounds to 7 centimeters. So the correct choice is B, 7 centimeters.
