Final answer:
Cheryl drove a total of 900 miles over two days, assuming Austin to Fort Worth is 200 miles one way and Austin to Jackson is 500 miles. The distance is already rounded to the nearest ten and hundred miles, which is 900 miles in both cases.
Step-by-step explanation:
To find the total distance Cheryl drove, we need to know the distances between Austin and Fort Worth, and Austin and Jackson. Since these specific details are not provided in the question, we will consider hypothetical distances for the purpose of this explanation. Let's assume that the distance from Austin to Fort Worth is about 200 miles one way. On Monday, Cheryl drove this distance twice, once to Fort Worth and back to Austin, accumulating 400 miles. On Tuesday, let's assume the distance from Austin to Jackson is approximately 500 miles. Therefore, Cheryl drove another 500 miles on Tuesday.
The total distance Cheryl drove over the two days is the sum of Monday and Tuesday's distances. So, the total distance driven by Cheryl is 400 miles plus 500 miles, which equals 900 miles.
To round to the nearest ten, we have 900, which is already rounded to the nearest ten. To round to the nearest hundred, we would round 900 to 900 miles as well.
