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.
