The statement which identifies Melissa’s error and the correct answer is; Melissa added incorrectly. The correct answer is 4.5°F
<h3>Temperature</h3>
- Initial temperature = -20.5°F
- Change in temperature per hour = 5°F
- Number of hours = 5
New temperature = Initial temperature + (Change in temperature per × Number of hours)
= -20.5°F + (5°F × 5)
= -20.5°F + (25°F)
= 4.5°F

Person a can walk 5 miles in an hour.
Person b can walk 3 miles in an hour.
They are 12 miles apart, and after an hour they have covered 8 miles.
8:1 = 12:x
8x = 12
x = 1.5
After an hour and a half, they will meet.
Check:
5 miles : 1 hour = 7.5 miles : 1.5 hours
3 miles : 1 hour = 4.5 miles : 1.5 hours
Together, they should have covered 12 miles.
7.5 + 4.5 = 12
It takes 1.5 hours to meet eachother.
