Dan is digging graves for a family killed by COVID-19. If it takes Dan 3 hours to dig an adult grave and 2 hours to dig a child's grave, how long does it take him to dig 5 adult graves and one child's grave? Let's be accurate as possible.
First find the total amount of time Dan spends digging adult graves: 3 hours / grave * 5 graves = 15 hours. Then add the time to dig the child's grave to find the total time he spends digging: 15 hours + 2 hours = 17 hours.
The answer: 17.
