Answer: She rode 12.5 miles per hour .She rode 12.5 miles per hour .

She will take 0.36 hours to go 4.5 miles.

Step-by-step explanation:

Given : A  cyclist rode 3.75 miles in 0.3 hours..

Here , distance = 3.75 miles

Time = 0.3 hours

Then,  Speed = [tex]\dfrac{\text{Distance}}{\text{Time}}[/tex]

[tex]=\dfrac{3.75}{0.3}\\\\=12.5\text{ miles per hour}[/tex]

That means : She rode 12.5 miles per hour .

Now , with the same rate the time taken by her to go 4.5 miles = [tex]\dfrac{\text{Distance}}{\text{Speed}}[/tex]

[tex]=\dfrac{4.5}{12.5}=0.36\text{ hour}[/tex]

Hence, she will take 0.36 hours to go 4.5 miles.
