Hey there! I'm happy to help!
28(5280)=147840 feet per hour.
There are 60 minutes in an hour. To find out how many feet Bolt runs in a second we divide by 60.
147840/60=2464
And we divide by sixty again to get to seconds.
2464/60=41 1/15 feet per second.
Have a wonderful day! :D

Answer:
n = 2
Step-by-step explanation:
1/2(n-4) - 3=3- (2n+3)
Expand the brackets.
1/2n-2-3=3-2n-3
Add or subtract the like terms.
1/2n-5=-2n
Add 2n and 5 on both sides.
1/2n+2n=5
Add like terms.
5/2n = 5
Multiply both sides by 2/5.
n = 5 × 2/5
n = 10/5
n = 2
10.51 is the answer when you round to the nearest hundredth.
