Complete question :
Roger built a model car of a station wagon he actually owns. Based on the ratio on the box, he knows that every inch in the length of his model car represents 25 inches of length in his actual station wagon. The station wagon's car manual shows that the length of the actual car is 193.75 inches.
Complete the following equation so that it can be used to find the length, m, of the model car, then find the length of the model car.
The length of the model car is _ inches
Answer:
7.75 inches
Explanation:
Scale factor from the question is :
1 inch : 25 inches
Length of actual car = 193.75
The length of the model car = m
If :
1 = 25
m = 193.75
Using cross multiplication :
25m = 193.75
Divide both sides by 25
25m/25 = 193.75 / 25
m = 7.75 inches
