We will first convert lb to grams and in³ to milliliters.
350 lb : 2.205 = 158.75733 kg = 158,757.33 grams
1.3 · 10^4 in³ = 13,000 in³ = 13,000 · 0.016387064 = 213.031 liters
213.031 liters · 1,000 = 213,031 milliliters
Density = m / V = 158,753.33 g / 213,031 ml = 0.7452 g/ ml

HOPE THIS HELPS
Since Speed, V = Distance/Time
Average speed = Total Distance/Total Time
From the given data, Total Distance = 100 + 30 + 75 miles
and Total Time = 2 + 1 + 1 hours
Average Speed = 205/4
Average Speed = 51.25 mph ( or 51mph to the nearest whole number)
Answer:
C. melting
option C is correct answer.
Answer:
The average distance is 999.936 light years.
Solution:
As per the question:
Ours is the Milky Way Galaxy with the diameter:
D = 1,00,000 ly
Radius, R = 
Now,
A = 
The area to each civilization, A' is:
A' = 
The radius of each area of civilization, r:
Thus the average separation distance between civilizations is given as:
2r =
