Question

Tony finishes baking cookies at 10:33 am he started at 7:18 am now long was he baking cookies?

Answer 1

To find the amount of time between two events, we can use subtraction, just like we do with regular subtraction problems. The subtraction will look something like this:

  10:33
-
  7:18

Like in a regular subtraction problem, we can subtract the digits that line up, like 10 and 7. Subtracting all of the corresponding digits, we get that it took Tony 3 hours and 15 minutes to finish baking the cookies. 

Answer 2

Tong took 3 hours and 15 baking cookies
