Question

A model car is 3 3/4 inches long using a scale of 1/2 in = 2feet find the actual length of the car

Answer 1

15 feet

Explanation:

Set up a proportion where x is the actual length of the car:

`(3(3)/(4) )/((1)/(2) )` =
`(x)/(2)`

Cross multiply and solve for x:

`(1)/(2)`x = 7
`(1)/(2)`

x = 15

So, the actual length of the car is 15 feet
