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

Step-by-step 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}}{(8)/(3)\text{hour}} \end{gathered}`
`\begin{gathered} =\text{ 108miles }/\text{ 8/3hour} \\ u\sin g\text{ the KCF: k}eep\text{ change flip method} \\ =108*(3)/(8) \\ speed=40.5 \end{gathered}`

Aaliyah is going at a speed of 40.5miles per hour
