Answer 2

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.

Explanation:

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

Here , distance = 3.75 miles

Time = 0.3 hours

Then, Speed =
`\frac{\text{Distance}}{\text{Time}}`

`=(3.75)/(0.3)\\\\=12.5\text{ miles per hour}`

That means : She rode 12.5 miles per hour .

Now , with the same rate the time taken by her to go 4.5 miles =
`\frac{\text{Distance}}{\text{Speed}}`

`=(4.5)/(12.5)=0.36\text{ hour}`

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