1. tom arrived to work at 8:15 a.m. how long does he have before the morning meeting?

tom has hour(s) and minute(s) before the morning meeting.
(type a whole number.)

Explanation:

Step1: Identify start and end times

Tom arrives at 8:15 A.M., morning meeting starts at 10:10 A.M.

Step2: Calculate time difference

Subtract arrival time from meeting start time.
10:10 - 8:15. First, convert 10:10 to 9:70 (borrow 1 hour = 60 minutes).
9:70 - 8:15 = 1 hour and 55 minutes? Wait, no: 10:10 - 8:15. Let's do hour and minute separately.
Hours: 10 - 8 = 2, but minutes: 10 - 15 is negative, so borrow 1 hour (60 minutes) from hours. So 9 hours and 70 minutes - 8 hours and 15 minutes = (9 - 8) hours + (70 - 15) minutes = 1 hour 55 minutes? Wait, no, wait: 8:15 to 9:15 is 1 hour, then 9:15 to 10:10 is 55 minutes. So total is 1 hour + 55 minutes? Wait, no: 8:15 to 10:15 is 2 hours, but the meeting starts at 10:10, which is 5 minutes before 10:15. So 2 hours - 5 minutes = 1 hour 55 minutes. Wait, but let's check again.
8:15 A.M. to 10:10 A.M.
From 8:15 to 9:15: 1 hour.
From 9:15 to 10:10: 55 minutes (because 10:10 - 9:15 = 55 minutes).
So total time is 1 hour + 55 minutes = 1 hour 55 minutes? Wait, no, 8:15 to 10:10: 10:10 - 8:15 = (1060 +10) - (860 +15) = 610 - 495 = 115 minutes. 115 minutes is 1 hour (60) + 55 minutes. So yes, 1 hour and 55 minutes? Wait, but the problem says "hour(s) and minute(s)". Wait, maybe I made a mistake. Wait, 8:15 to 10:10. Let's count:

8:15 to 9:15: 60 minutes (1 hour)
9:15 to 10:10: 55 minutes (because 10:10 - 9:15 = 55 minutes: 60 -15 +10 = 55? Wait, 9:15 to 10:00 is 45 minutes, then 10:00 to 10:10 is 10 minutes, so 45 +10 = 55 minutes. So total 60 +55 = 115 minutes = 1 hour 55 minutes. Wait, but the problem's answer boxes: one for hour(s), one for minute(s). Wait, maybe I miscalculated. Wait, 8:15 to 10:10. Let's do 10:10 - 8:15.

10 hours 10 minutes - 8 hours 15 minutes = (10 - 8) hours + (10 - 15) minutes = 2 hours -5 minutes = 1 hour 55 minutes. Yes. So hours: 1, minutes: 55. Wait, but the problem says "Type a whole number" for each. So hour is 1, minute is 55? Wait, but let's check again. Wait, 8:15 to 10:10. Let's use minutes:

8:15 is 8*60 +15 = 495 minutes.
10:10 is 10*60 +10 = 610 minutes.
610 - 495 = 115 minutes.
115 minutes = 60*1 + 55, so 1 hour and 55 minutes. So the hour is 1, minute is 55. Wait, but the problem's first box is "hour(s)" with a dropdown, and the second is "minute(s)". So the answer is 1 hour and 55 minutes? Wait, but maybe I made a mistake. Wait, 8:15 to 10:10: let's count the hours and minutes.

From 8:15 to 10:15 is 2 hours. But the meeting is at 10:10, which is 5 minutes before 10:15. So 2 hours minus 5 minutes is 1 hour 55 minutes. Yes. So the number of hours is 1, minutes is 55.

Answer:

1 hour(s) and 55 minute(s)
