A model of a car has a scale of 2in: 3ft. If the actual length of the car is 20 ft, what is the length of the model

Answer 1

2in : 3 ft

=2 in:3*12 in

=2 in: 36 in

= 1:18

20 ft = 240 in

1/18 = x inches /240 inches

cross multiply

x = 13 1/3 inches

Answer 2

Use a ratio to find the model length. If x = the model length

Then,

2 inches/3 feet = x inches/20 feet

Solving for x: x = 2(20)/3 = 40/3 = 13.33 inches
