#### Answer

The car moves $\approx 751$ ft along the roadway.

#### Work Step by Step

1. Use the Pythagoras Theorem to solve for the roadway ($x$)
$a^{2} + b^{2} = x^{2}$
$45^{2} + 750^{2} = x^{2}$
$2025 + 562500 = x^{2}$
$564525 = x^{2}$
$\sqrt (564525) = x$
$x = 751.348...$ ft
$x \approx 751$ ft
