Answer 1

Answer:

Step-by-step explanation:

I'll do the first one to get you started

# 1

2/21 = 9/x

2x = 21*9

2x = 189

x = 189/2

x = 94.5

So the actual distance that 9 cm represents is 94.5 km

Answer 2

Answer:

2/21=3.6/x

2x=3.6*21

2x=75.6

x=37.8

So the actual distance that 3.6 cm represents is 37.6 km
