Average speed = Total distance/Total time.
First drive:
120/60=2 (distance/rate=time)
Second drive:
120/40=3 (distance/rate=time)
Average:
Total time=120+120=240
Total time=3+2=5
Average speed = Total distance/Total time=240/5=48
His average speed was 48 mph.

−2x(−10x+1)
Apply the distributive law:
Ex. of distributive law:
a(b+c)= ab+ac
-2x(-10x)+(-2x)*1
Apply minus/plus rule:
2*10xx-2*1*x
Simplify 2*10xx-2*1*x:
2*10xx= 20x^2
2*1*x= 2x
20x^2-2x
Your Answer Is 20x^2-2x
