A new company wants to test out a pill that will unlock all of your brain to make you 50% smarter and much more efficient. What is the control group in this experiment?

I believe it is how smart the brain is before the pill experiment?

Step-by-step explanation:

the brain smartness level before the experiment is the standard from which the brain smartness level AFTER the experiment is compared to.

45.36 feet per second

step-by-step explanation:

tyrone travels 30 miles in 58.2 minutes.  

1 mile = 5280 feet; this means he travels

30(5280) = 158400 feet in 58.2 minutes.

1 minute = 60 seconds; this means he travels 158400 feet in

58.2(60) = 3492 seconds.

this gives us the unit rate of

158400/3492 = 45.36 feet per second.
