Answer:
D.
2(6x + 5+ 2y)
Step-by-step explanation:
12x + 10 + 4y
Factor out a 2
2(6x+5+2y)
Volume of a sphere is 4/3(pi r ^3)
You were given d = 10 so r = 5
Then just plug and chug
1 mile = 1.6 kilometers so 24*1.6 = 38.4
<em>24 miles = 38.4 kilometers</em>
1 kilometer = 1000 meters so 38.4*1000 = 38,400 meters
<em>38.4 kilometers = 38,400 meters
</em>1 hour = 60 minutes so 2*60 = 120
<em>2 hours = 120 minutes
</em>
To calculate meters per minute, divide.
38,400 / 120 = 320
So that means that Calvin's approximate speed is 320 meters per minute.
