Answer:
1) [tex]x = 30\,in[/tex], 2) [tex]x = 75\,mi[/tex], 3) [tex]x = 31\,mi[/tex]
Step-by-step explanation:
The actual distances are computed below:
1) The actual distance is:
[tex]x = \frac{3\,in}{1\,in}\times 10\,mi[/tex]
[tex]x = 30\,in[/tex]
2) The actual distance is:
[tex]x = \frac{7.5\,in}{1\,in}\times 10\,mi[/tex]
[tex]x = 75\,mi[/tex]
3) The actual distance is:
[tex]x = \frac{3.1\,in}{1\,in}\times 10\,mi[/tex]
[tex]x = 31\,mi[/tex]
