Answer:
The approximate length of the actual car is <u>43 feet</u>.
Step-by-step explanation:
Given:
The scale on a model railroad train set is 3.5 millimeters to 1 foot. If the length of a model car in the set is 150 millimeters.
Now, to find the approximate length of the actual car.
Let the actual length of the car is
The length of a model car in the set is 150 millimeters.
As, given the scale on a model railroad train set is 3.5 millimeters to 1 foot.
<em>So, 3.5 millimeters equivalent to 1 foot.</em>
<em>Thus, 150 millimeters to </em><em>.</em>
Now, to get the actual length of the car by using cross multiplication method:
<em>By using cross multiplying we get:</em>
<em>Dividing both sides by 3.5 we get:</em>
<em><u>The approximate length of the actual car = 43 feet.</u></em>
Therefore, the approximate length of the actual car is 43 feet.
