The art teacher needs to buy at least 8 packs of 8 brushes.
Step-by-step explanation:
Every pack has 8 brushes. She needs AT LEAST 60 so she cannot have less than 60 brushes but can have more than 60. 8 x 8 =64 so she would have 4 bushes left over. She needed to buy 8 packs so she can have at least 60.
Total distance traveled by Fernando's family = 272 miles
Time taken to travel the distance of 272 miles = 4 hours
Then we can say that
The distance traveled by Fernando's family in 4 hours = 272 miles
So
The distance traveled by
Fernando's family in 1 hour = (272/4) * 1 miles
= 68 miles
From the above deduction we can easily conclude that Fernando's family traveled at a rate of 68 miles per hour. I hope to have helped you.
