Answer: 60y+48
12•5y=60y
12•4=48
-7y - 6y³ + 2y + 4y³ - 5 -1 - 2y³
= -4y³ - 5y - 6 //Combine like terms.

Answer: 30 mph is the answer.
Step-by-step explanation:
s = 3 miles
t = 6 minutes
so,
60 minute = 1 hour
1 minute = 1/60 hour
6 minutes = 1/60 * 6 = 0.1 hour
so
average speed = s/t
= 3/0.1 = 30 mph
