Answer 1

10 9/28

Explanation:

To find the total number of hours Kelly flew, we need to add the time it took her to fly from city A to city B and the time it took her to fly from city B to city C.

Given:

- It took 7 3/4 hours to fly from city A to city B.

- It took another 2 4/7 hours to fly from city B to city C.

First, let's convert the mixed numbers to improper fractions:

- 7 3/4 hours = 31/4 hours

- 2 4/7 hours = 18/7 hours

Next, we can add the fractions together:

31/4 hours + 18/7 hours = (31*7 + 4*18) / (4*7) = (217 + 72) / 28 = 289/28 hours

Now, let's simplify the fraction:

289/28 hours = 10 9/28 hours

Therefore, Kelly flew a total of 10 9/28 hours from city A to city C.
