To find out how long Bob was baking cookies, we must calculate the difference between his finish time and his start time.
First, calculate the minutes difference:
Finish time: 10:51 a.m. = 10*60 + 51 = 651 minutes
Start time: 6:29 a.m. = 6*60 + 29 = 389 minutes
Next, calculate the total baking time:
Total baking time = Finish time - Start time
Total baking time = 651 minutes - 389 minutes
Total baking time = 262 minutes
Therefore, Bob was baking cookies for 262 minutes.
Bob finished baking cookies at 10:51 a.m. He started at 6:29 a.m.
