Answer:
The answer is the third option: [tex]\dfrac{4.5}{32}=\dfrac{x}{54}[/tex]
Step-by-step explanation:
The rate must be the same, and the rate is expresed by distance/time.
In the first case, distance=4.5 and time=32, so the rate is [tex]\dfrac{4.5}{32}[/tex] and must be equal to the rate [tex]\dfrac{x}{54}[/tex] given that x is the distance and the time is 54 minutes.
