Sonya traveled 12000 feet in 4 minutes, so her average speed is 3000 feet per minute. This calculation is reasonable when checking through dimensional analysis.
The subject of this question is average speed which is part of Physics topic in Mathematics. To solve the problem, we'll first figure out the distance Sonya traveled and the time it took. Sonya passed marker 20 at 3:14 P.M and marker 8 at 3:10 P.M, giving us 4 minutes. The markers are every 1000 feet, so from marker 8 to 20, she traveled (20-8) * 1000 = 12000 feet. Therefore, Sonya's average speed is the distance traveled divided by the time it took which is 12000 feet / 4 minutes = 3000 feet/minute.
For dimensional analysis, we can check the reasonableness of our result. The units of speed should be in a form of distance over time. In our answer, we have feet per minute, which fits the requirement, so our calculation is reasonable.

t - 6(-2t + 1)
The correct expression which is equivalent to this expression t - 6(-2t + 1) is,
⇒ 13t - 6
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
We have to given that;
The expression is,
⇒ t - 6 (- 2t + 1)
Now, We can simplify as;
⇒ t - 6 (- 2t + 1)
⇒ t + 12t - 6
⇒ 13t - 6
Thus, The correct expression which is equivalent to this expression
t - 6(-2t + 1) is,
⇒ 13t - 6

The expression that shows the temperature in °C is .
Step-by-step explanation:
Step 1:
The initial temperature at 6.00 am was °C.
Step 2:
From 6.00 to 7.00 am, the temperature increased by another 2.5°C, so the temperature at 7.00 am was °C.
Step 3:
From 7.00 to 8.00 a.m, the temperature decreased by another 0.25°C, so the temperature at 8.00 am was °C.
Step 4:
From 8.00 to 11.00 a.m, the temperature dropped by another 3.25 °C, so the temperature at 11.00 am was °C which is represented by the fourth option.
