distance: _______ ft

Answer 1

Answer:

482.2 ft.

Explanation:

Hello!

In this case, considering that Charlotte drives at 69.8 mi/h, the first thing we need to do is to convert that velocity to ft/s as shown below:

$69.8\frac{mi}{h}*\frac{5280ft}{1mi} *\frac{1h}{3600s}=102.37\frac{ft}{s}$

Thus, the travelled distance is obtained by multiplying the new velocity by the elapsed time:

$d=102.37\frac{ft}{s} *4.71s\\\\d=482.2ft$

Best regards!
