Answer:

a. 3 cm

b. 6 km

Step-by-step explanation:

to be completely honest, I just shoot my answer based on the pattern.

if you notice that when the scale is 4 cm, the actual distance is 5 km. When the distance is 4 km, the scale should probably be 3 cm. It's the same with the 5 cm scale, then the distance should be 6 km

Step-by-step explanation:

Use ratios to solve it

a)

  • 4 cm → 5 km
  • x cm → 4 km

x = 4*4/5 = 3.2 cm

b)

  • 4 cm → 5 km
  • 5 cm → x km

x = 5*5/4 = 6.25 km
