a. 0.36

Answer 1

The cyclist's speed is 12.5 miles per hour and it would take her 0.36 hours to go 4.5 miles.

Step-by-step explanation:

To find the cyclist's speed in miles per hour, we need to divide the distance traveled (3.75 miles) by the time taken (0.3 hours). Dividing 3.75 by 0.3 gives us 12.5 miles per hour. So, the correct answer is a. 12.5.

To find how long it would take the cyclist to go 4.5 miles at this rate, we can divide the distance (4.5 miles) by the speed (12.5 miles per hour). Dividing 4.5 by 12.5 gives us 0.36 hours. So, the correct answer is a. 0.36.
