at that rate she will travel 4.5 miles in 21 minutes and 36 seconds.
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.
