The correct answer isn't given for the first problem. 60 out of 1200 is not 60 percent.
Your second and third answers are not correct.
Please try again.

first one:
60/1200 = 0.05 = 5%
You must have a typo in your answer choices.
second one: 800/20000 = .04 = 4% not 4.5%
third one: I got 21 feet 8 inches
