Question

A doctor sees each of her patients for 15 minutes. How many patients can she see in 4-1/2 hours?
18
19
20
30
none

Answer 1

To determine how many patients the doctor can see in 4-1/2 hours, we first convert the time to minutes:

4-1/2 hours = 4.5 hours = 4.5 × 60 minutes = 270 minutes.

Since each patient takes 15 minutes, we can divide the total minutes by the time taken for each patient:

Number of patients = Total minutes / Minutes per patient
Number of patients = 270 minutes / 15 minutes per patient
Number of patients = 18.

Thus, the doctor can see **18** patients in 4-1/2 hours.
