Answer:
C. 400 miles
Step-by-step explanation:
In each hour, it travels 80 miles. (That is the meaning of "80 miles per hour.") So you can add up the distances over a period of 5 hours:
80 miles + 80 miles + 80 miles + 80 miles + 80 miles
After the first sum (80+80=160), you can see what the correct answer will be. Continuing, you find the sum to be ...
= 400 miles
___
Multiplication was invented to make repeated addition easier.
5 × 80 miles = 400 miles
_____
Strictly speaking, you are multiplying numbers with units here:
(5 h) × (80 mi/h) = 400 mi·h/h = 400 mi . . . . . . the units h/h cancel
Given,
The turkey was cooked in the oven for 3 hours.
The internal temperature rose from 30 degress F to 156 degrees F.
Average rise in temperature per hour = Total rise in temperature/ total number of hours
Average rise in temperature = 156 degrees F – 30 degrees F= 126 degrees F
Total number of hours = 3 hours
Average rise in temperature per hour = 126 degrees F/3 hours= 42 degrees F/hour
