She went 3.5 feet per second down for 90 seconds
3.5*90 = 315 feet below
2.2*30 = 66 feet up
315-66 = 249 feet below.

So, she must go up at 4.8 feet per second.
249/4.8 = 51.875 seconds
52 seconds when rounded

First of all you would multiply 9(days) by $66(per day) which would be $594! The, you would add $15.99 for insurance which would be $609.99, and then also add 42.50 to fill up with gas. So your answer would be $652.49. Hope I helped
