What is the
because i don't get the answer for the one that pops up

I think it's 52.5 seconds
Divide 180 by 24 to get 7.5, then multiply 7.5 by 7 to get the 52.5

Okay so in total there is 180 feet. The person travels 24 feet every 7 seconds. So, you would divide 180 by 24. You should get the answer 7.5 so seven and a half seconds. Now multiply 7.5 by 7 you should get 52.5 seconds.
I'm pretty sure this is how you would find the answer to that, if I'm wrong let me know.
