Distance = 250 miles, time spent = 4.5 hours
AVERAGE SPEED = DISTANCE/TIME
So AVERAGE SPEED =250/4.5 = 55.55 mi/h. The closest is 56 mi/h
Answer: r=7x-1/8
Step-by-step explanation:
2(4r+3)=7x/2+5/2
4r+3=7x+5/2
4r+3-3=7x+5/2 -3
4r=7x+5/2 -3
4r/4= 7x-5/2/4 -3/4
r=7x-1/8

Answer: 8:30, 16:60, 32:120
Answer:
radius = 30 in
Step-by-step explanation:
EF = circumference × fraction of circle, substitute values
5π = 2πr ×
← where r is the radius
5π = 2πr × 
Multiply both sides by 12 to clear the fraction
60π = 2πr ( divide both sides by 2π )
= r, thus
r = 30 in
