Answer :
Set up a proportion.
2/30 = 7.5/x
Cross multiply:
2x = 225
Divide 2 to both sides:
x = 112.5
So the actual distance between the two cities is 112.5 miles.
2/30 = 7.5/x
Cross multiply:
2x = 225
Divide 2 to both sides:
x = 112.5
So the actual distance between the two cities is 112.5 miles.
Cross multiply: [tex] \frac{2}{7.5} = \frac{30}{x} [/tex]
[tex]225 = 2x[/tex]
Divide 2 from both sides
[tex] \frac{225}{2} = \frac{2x}{1} [/tex]
[tex]x =112.5[/tex]
Your answer is C. 112.5
[tex]225 = 2x[/tex]
Divide 2 from both sides
[tex] \frac{225}{2} = \frac{2x}{1} [/tex]
[tex]x =112.5[/tex]
Your answer is C. 112.5
