The interval time, i, in minutes, between appointments is related to total number of minutes t that a doctor spends with patients in a day, and the number of appointments n, by the formula: i
equals
=1.08 (t/n).
if a doctor wants an interval time of
16
16 minutes and wants to see
21
21 appointments per day, how many hours a day should the doctor be prepared to spend with patients?

Approximately 5.19 hours.

Step-by-step explanation:

The question is asking that you solve for T (the amount of time spent with patients in a day). To do so, simply input the values which it has given you for your variables. We can substitute 16 for I as that is the doctor's preferred interval time and we can substitute 21 for N as that is the amount of appointments the doctors wishes to have per day.

To solve, start by multiplying both sides by 21.

Next, divide both sides by 1.08.

Your answer comes out to 311.11 minutes. The question is asking for this to be translated into hours per day, which equates to approximately 5.19 hours.

9 sandwiches per hour

step-by-step explanation:

when we have a rate, we want a 1 in the denominator

27/3 = 9

27 sandwiches/ 3 hours = 9 sandwiches/hour
