Answer:
8mph
Step-by-step explanation:
Let call X is trip there speed
R x t = D
# to X 3 = 3X
# Return 6 4 = 24
Because the distance when we go to and back are the same, so we have:
3X = 24
<=> X = 8
So the avergage speed of the trip there is 8mph
Answer:
0.2
Step-by-step explanation:

The chocolate chip cookies of the cookie's club are not perfect according to Wendy, as the ratio of the chocolate chips to the cookies is more than that of a perfect cookie.
To solve this problem we have to learn about ratio. A ratio is an ordered pair written as or a:b where . It can also be defined as the number of times one number is contained in another number.
In the given problem Wendy thinks that a 353535 chocolate chips are essential for 555 cookies so that each cookie is perfect. Now let us find the ratio of the chocolate chips for each cookie.
Ratio=
or, Ratio=637:1
Therefore according to Wendy, a perfect chocolate chip cookie must have 637 chocolate chips.
Now let us find the ratio of the chips to cookie of the Cookie's Club.
Total chocolate chips=100100100
Total cookie=151515
Ratio of chips to cookies= which can be simplified to .
Therefore required ratio=
or, approximately ratio=
Now
Therefore the chocolate chip cookies of the cookie's club are not perfect according to Wendy.
