Answer 1

Answer:

x = 105 km

Step-by-step explanation:

We can use ratios to solve

1 cm               15 cm

------------ = ------------

7 km            x km

Using cross products

1 * x = 7 * 15

x = 105 km

Answer 2

Answer:

$105km$

c

Step-by-step explanation:

$1cm = > 7km \\ 1cm = > 700000$

$1 : 70000$

$1cm = > 700000cm \\ 15cm = > x$

$\: 1 \: \: \: : 700000 \\ 15 : x$

Use cross multiply

$\\ 1x = 15 \times 700000 \\ x = 10,500,000$

so,

$1cm = > 700000cm \\ 15cm = > 10,500,000 cm$

$15cm = 10,500m \\ 15cm = 105km$

hope this helps
