Answer
$\rm4\; m\approx 13 \;ft$
Work Step by Step
We can say that the length of a typical car is 4 meters.
$\rm 4\;m=4\;\rm m\cdot \left(\dfrac{39.37\;in}{1\;m}\right)\cdot\left(\dfrac{1\;ft}{12\;in}\right) $
The units of $\rm m$ and $\rm in$ cancel and the unit of $\rm fr$ remains.
Thus,
$\boxed{\rm 4\;\rm m\approx 13.12\;\rm ft}$
We arrived to this estimate by assuming that the length of the car is double the width of the car and that the width of the car is 2 meters.
