Once again, I have some confusing problems for math. If you know any answers, even if you only know one, please tell me the answer and walk me through it so I can actually understand how you get to it. Thanks!
#1: A space craft travels at a speed of 8/10 of a mile per second. How many days does it take it to travel from the Earth to the Moon, a distance of 240,000 miles?
At first, my answer I got was 208 1/3 days, but to me that sounds way to long for a spacecraft, considering how fast it is going. The other possible answers I got are that maybe I need to move the decimal point, so maybe 20.8 days or 2.08 days. Please tell me if any of these answers are right.
#2: How much force, in g•cm/s² (that's to the second power, if you can't read that symbol) is exerted by a golf ball striking a tree while accelerating at 20 cm/s²? Show how you can solve this problem without knowing that F = ma.
Of course, I don't even know what in the world F = ma is. Okay, my sister told me it means Force equals mass times acceleration, but I wouldn't even know how to apply it to this problem.
Try to solve this problem. It did say in the problem a golf ball like the one in problem #9 on my worksheet, so if you need more info to solve this problem, I can give you problem #9, too.
I appreciate any help you can give me. Thank you!

so how many seconds are in a day?
60sec/min*60min/hr*24hrs/day=86400sec/day
So how fast is it going?
8/10 mi/sec*86400sec/day=? mi/day
So how long does it take?
timeindays=distanceinmiles/speedinMi/day 
Thanks! Could you explain how you got your answer a little more and give me the numbers, too? Do you have any idea for the answer to number 2? Thanks so much!
