Hank finished bowling at 6:05. To figure this out it’s easiest to subtract the hours first. If he finished at 8 but started 2 hours earlier then all you have to do is subtract 2 from the prime finishing number, aka 8. So, now we know that it’s 6:00, but you can never forget about the minutes. Subtract 20 from 15 and your answer will be 5!
