Answer:
The volume of the prism is 22m
They both don't have the same number of zero as the answer because you are doing 40x500 which 20000 and 4x600 which is 2400
Let the speed for the first 12 mi be x mi/h, the speed for 18 mi was (x+4) mi/h
thus given that
time=distance/speed
the average time will be:
3=(12+18)/(x+x+4)
3=30/(2x+4)
solving for x we get
3(2x+4)=30
6x+6=30
6x=24
x=4 mi/hr
Answer: 12 mi/hr
The answer is c 109 degrees
