Answer:
Step-by-step explanation:
To find out how many times Joey rang the bell, we need to find the total number of minutes between the times 6:15 and 7:45.
6:15 is 6 hours and 15 minutes, which is 660 + 15 = 375 minutes
7:45 is 7 hours and 45 minutes, which is 760 + 45 = 465 minutes
So the total number of minutes between 6:15 and 7:45 is 465 - 375 = 90 minutes.
Since Joey was required to ring the bell every 15 minutes, he would have rung the bell 90 / 15 = 6 times.
