Step-by-step explanation:
Dimensional analysis: dividing out common units like dividing out common factors
<em>For ex: </em>3/5* 5/7= 3/7
cross out the fives and turn them into 1
For dimensional analysis you just cross out the units.
days-->hours-->minutes
462.25d/1* 24h/1d* 60m/1h= 665,640 minutes
Cross out the d's and h's.
You are left with minutes on the top and no units on bottom.
Just multiply across to get the answer 665,640 minutes

Step-by-step explanation:
Calculate the length of the outside of the tire, which is the circumference of the tire.
Circumference = 2 x radius x PI
Circumference = 2 x 0.45 x 3.14 = 2.83 meters.
It travels 2.88 meters per second.
Divide the circumference by the amount of travel:
2.83 / 2.88 = 0.98 seconds to make one revolution.
