Adrian drives to school and back each day. The school is 16 miles from his home. He averaged 40 miles per hour on his way to school. If his total trip takes 1 hour, at approximately what average speed does Adrian drive home?

26 mph

Step-by-step explanation:

First find the time Adrian takes to get to school

I found it easiesT to use the method of ratio and proportion

40:60

16:x

x= 16 x 60 / 40 = 24 minutes

So, he has 60-24 minutes to return home, that is 36

What is his speed if his time is 36 minutes= 0.6 hours

Speed = Distance divided by time = 16/0.6 = 26.6 miles per hour.

Hope this helps

Good Luck

i think it would be 42cm

( - 4 , -7 )

all the lines must parallel  

step-by-step explanation:

coordinates of c = ( - 1 , 2 )

3 units left = ( -4 , 2 )

9 units down = ( - 4 , 11 )
