a=180-360/n +360/n
360/n=180-a -a
?
am i doing this right so far? Also im not sure of the next step. After i got to this point i didnt know what to do

Question 153613: hi,
my name is jay, and i am struggling with this question. the question is:
if a pitcher throws a baseball 90 miles per hour, how many seconds does it take for the ball to reach home plate?
here's what i've tried:
time equals distance divided by speed
i divide 60.5 feet by 90 mph, and i get .6722 seconds.
Then i thought, can i really solve this equation this way? can i use feet in distance as the numerator and miles per hour in divisor. I'm not sure how to solve this.
thank you so much for your time. Jay
