Part A)
The coin landed on heads 9 times out of 30 flips, so the experimental probability is 9/30, which reduces to 3/10 probability.
Part B)
Theoretically a coin has a 1/2 probability of landing on heads each flip
5 m/sec or 300m / min
using speed = 
change 5 min 20 sec to seconds = (5 × 60) + 20 = 320 sec
speed =
= 5m / second or
speed = 60 × 5 = 300m / minute
If someone reads the book (Gryphon) by Charles baxter what???
no thanks but I'll see if I can get friends to join
