Miriam painted her pots from 6:45 AM to 8:00 AM. How long did she painted her pots (in minutes)?

From 6:45 AM to 8:00 AM, we have 1 hour and 15 minutes.

  8:60 AM
- 6:45 AM
----------------
  1 15

⇒ 1 hour = 60 minutes

1 hour and 15 minutes
60 minutes + 15 minutes
75 minutes

Miriam painted her pots for 75 minutes.

Given:
           The range of time spent for painting the pots = 6:45 AM - 8:00 AM
            
Find:  The time taken for Miriam to painter her pots in minutes.
Solution:

Objective 1: Find the number of hours taken.
          Step 1: Subtract the hours.
          Step 2: Subtract the minutes. 
                   If the difference is negative:
             ∞ Add 60 to the difference.
             ∞ Subtract 1 from the difference of Step 1.

Actual Operation:
 
           Time:    6:45 AM - 8: 00 AM 
( Hour numbers: 8 and 6 ) ( Minute numbers: 0 and 45 )
                 
  Step 1:      8 - 6 = 2
  Step 2:      0 - 45 = -45    (The difference is negative so we.....)
             ∞ -45 + 60 = 15 minutes
             ∞  2 - 1 = 1 hour

We have 1 hour and 15 minutes but, we have to change the all to minutes.

1 hour and 15 minutes = 1 hour + 15 minutes
( We know that there are 60 minutes in 1 hour so we just substitute it.)

1 hour + 15 minutes = 60 minutes + 15 minutes

                            = 75 minutes
  Final Answer:  
                          75 minutes
