SHOW WORK!!!!!(question) There are markers every 1000 feet along the side of the road. While driving, Sonya passes marker 8 at 3:10 P.M. and marker number 20 at 3:14 P.M Find Sonya's average speed in feet per minute. Use dimensional analysis to check the reasonableness of your answer.
ANY ANSWERS THAT DO NOT HELP WILL BE REPORTED AND OR DELETED

Answers

1. Find the distance Sonya traveled:
20-8=12
12x1000feet=12000feet
2. Find the time it took Sonya to travel this distance:
Starting time: 3:10
Finish time: 3:14
Difference= 4min
3. Use the speed formula: S=D/T
S=12000feet/4min
S=3000feet/min

Final answer:

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.

Explanation:

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.

Answers

2 1/3 + 1 2/3 = 3 3/3

2 1/3 + 1 2/3 = 4
2 + 1 = 3; 1/3 + 2/3 = 1
3 + 1 = 4

3 3/3 = 4
3 = 3; 3/3 = 1
3 + 1 = 4

Now, let's come up with a fraction that is equal to 4.

2 6/3

This answer works because we already have 2 as an integer, and 6/3 is 2.
2 + 2 = 4
