Question

Adam drafts his favorite tractor trailer on a scale drawing. The drawing scale is 3 inches for each foot. If the drawing is 20 inches long, how long is the actual tractor trailer?

Answer 1

6.7 foot long. cos if you divide 20 by 3 the answer is 6.66666666667 and you around the first number up after the decimal place which gets you the answer of 6.7

Answer 2

Answer:

6.67 feet long

Step-by-step explanation:

The drawing scale is 3 inches per foot. If we have the amount of inches in length, we can determine the number of feet the actual tractor tailer is. We can do this by dividing 20 inches by 3 inches per foot to get the answer in feet:

$=(1/3)\cdot{20}=20/3=6.67$

The actual tractor trailer is 6.67 feet long from a scale of 3 inches per foot.
