The table below shows the different times it takes Paula to drive to work each day depending on the rate at which she drives.

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

2.625 hours

2.75 hours

3.125 hours

3.75 hours

From the values in the table, we can multiply the speed by the time to find out the amount of miles she travels a day. This is shown below:

30 mph * 2.5 hours = 75 miles

40 mph * 1.875 hours = 75 miles

50 mph * 1.5 hours = 75 miles

60 mph * 1.25 hours = 75 miles

Therefore, she travels 75 miles to work. Given a speed of 24 mph, we divide 75 miles by 24 to find out how long it takes her to travel that far:

75 miles / 24 mph = 3.125 hours
