If one day Paula rides a scooter to work at a constant rate of 24 miles per hour, how long should it take her?

3.125 hours.

Step-by-step explanation:

Let the distance between the home of Paula and her workplace is x miles.

Now, driving at the rate of 30 mph she covers this distance in 2.5 hours and hence the distance, x = (30 * 2.5) = 75 miles.

Now, if Paula rides a scooter to work at a constant rate of 24 miles per hour, then she will take (75 : 24) = 3.125 hours to reach her workplace. (Answer)

3.125 hours.
