Answer:
Yes, Emily is correct.
Step-by-step explanation:
If you have a - sign in front of a number in parenthesis that is negative, then what you are doing is taking the opposite of that negative number. Remember that the opposite of a negative number is a positive number. In this case, we want the opposite of negative five. What is that? It is +45, or 45. So yes, Emily is correct.

Convert to hours, then days, then years
60 minutes per hour
1000000/60=50000/3=16666.7 hours
24 hours per day
16666.7/24=694.4 days
365 days per year
694.4/365=1.9
the average person lives at least 1.9 years
