Question

A model of a car is 6.3 in. long. The scale of the model to that actual car is 1:30. What is the length of the actual car to the nearest foot?
A. 19 ft
B. 16 ft
C. 21 ft
D. 12 ft

Answer 1

8.13 is the actual legth of the car, unless i misuderstood the question.

Answer 2

Answer:

Option B. $16\ ft$

Step-by-step explanation:

we know that

The scale of the model to that actual car is equal to  $\frac{1}{30}\frac{in}{in}$

so

By proportion

Find the length of the actual car if the model of a car is $6.3\ in$. long

$\frac{1}{30}\frac{in}{in}=\frac{6.3}{x}\frac{in}{in}\\ \\x=30*6.3\\ \\x=189\ in$

Convert to feet

Remember that

$1\ ft=12\ in$

$189\ in=189/12=15.75\ ft$

Round to the nearest foot

$15.75\ ft=16\ ft$
