Answer:
12 mph
Step-by-step explanation:
First 30 miles while cycling at 15 mph. This means he spent 2 hours here.
Thus the 4 hours on the last 48 miles.
Average speed = distance / time
Average speed = 48 miles / 4 hours
Average speed = 12 mph
Therefore Regan's average speed is 12 mph for the last 48 miles.
Answer:
5 cups of walnuts are needed.
Step-by-step explanation:
This question can be solved using a rule of three.
One batch of walnut muffins uses 1 1/3 cups of walnuts.
So one batch of walnut muffins uses 
cups of walnuts.
How many cups of walnuts are needed to make 3 3/4 batches of muffins?
How many cups are required for 
batches.
1 batch - (4/3) cups
(15/4) batches - x cups
5 cups of walnuts are needed.
We know that his woodshed is a parallelepiped, and 8' is the depth, 16' is the lenght and 6' is the height.
A cord of wood is 4' high, 4' deep and 96" long.
96" = 8'
We find the volume of his woodshield.
V = h*d*l = 168*6 = 768 cubic feet
Find the volume of a cord
4*4*8 = 128 cubic feet
Do the ratio: 768/128 = 6
His woodshield can hold 6 cords.
For the second question, simply do a multiplication.
If 1 cord is $120, how much are 6?
120*6 = $720
