The answer is five! Don't tell me how I got that because my sister did the problem 2 minutes ago because I told her this question! Hope this help!
This is a guess using logic, but my answer for this is that she concluded that she walked faster in the first 15 minutes. An increase in speed would increase the distance she walked in that amount of time
= (7u³ + 8u² + 7) + (8u³ - 3u + 7)
Operate like terms together:
= 7u³ + 8u³ + 8u² - 3u + 7 + 7
= 15u³ + 8u² - 3u + 14
In short, Your Answer would be: 15u³ + 8u² - 3u + 14
Hope this helps!
