Answer:
Density of material would be 4.09 
units is 
Step-by-step explanation:
Given: The mass of a material is 45 grams and the volume of the material is 11 cubic centimeter
Density is defined as mass per unit volume.
It is given by:
where p is the density , m is the mass and V is the volume of the material respectively.
Here, Density is expressed in grams per centimeter cubed (g/cubic cm)
Here, m = 45 g , V = 11 cubic cm
We get;
= 4.09 
therefore, density of a material would be, 
and its units is 
Total miles:350+150=500
Total hours:4+3=7
Avg speed:500/7=71.429 mph
Answer:
