Question

Aaliyah drove 108 miles in 2 2/3 hours. On average, how fast did she drive, in miles per hour?

Answer 1

40.5miles per hour

Explanation:

distance = 108 miles

time = 2 2/3 hours

How fast means the speed

To get speed in miles per hour= distance/time

$\begin{gathered} \text{speed = }\frac{108miles}{2\frac{\text{ 2}}{3}\text{hours}} \\ =\text{ }\frac{\text{108miles}}{\frac{8}{3}\text{hour}} \end{gathered}$$\begin{gathered} =\text{ 108miles }\div\text{ 8/3hour} \\ u\sin g\text{ the KCF: k}eep\text{ change flip method} \\ =108\times\frac{3}{8} \\ speed=40.5 \end{gathered}$

Aaliyah is going at a speed of 40.5miles per hour
