Answer:
The correct answer is Cruz's running speed is 10 miles per hour and his biking speed is 16 miles per hour.
Step-by-step explanation:
Let the speed of Cruz when running is s miles per hour and speed of cruz biking is 1.6s miles per hour.
Cruz ran for 90 minutes and rode is bike for 135 minutes.
Total distance covered by Cruz is 
× s + 1.6s × 
This distance is given to be 51 miles.
⇒ × s + 1.6s × = 51
⇒ 90s + 216s = 3060
⇒ 306s = 3060
⇒ s = 10
Cruz's running speed is 10 miles per hour and his biking speed is 16 miles per hour.

Answer:
4 more pens
Step-by-step explanation:
Well, what do we know?
We know Sheila has:
6 pens
10 pencils
How many MORE pens does she need to make the number of pens <em>equal to </em>the number of pencils?
6 + x (x is the number of pens needed to EQUAL to 10)
6 + x = 10
x = 4
Sanity check:
6 + 4 = 10
Sheila needs 4 more pens to make the number of pens and pencils equivalent, or EQUAL TO each other.
Considering the volume of the aquarium, it is found that the length of the side of the base is of 9 feet.
<h3>What is the complete question?</h3>
Researching the problem on a search engine, it asks the length of the side of the base.
<h3>What is the volume of a prism?</h3>
The volume of a prism is given by the base area multiplied by the depth, that is:
V = Ab x d.
For this problem, the base is square, hence
Ab = s²
The volume and the depth are given as follows:
V = 648, d = 8.
Then:
8s² = 648
s² = 648/8
s² = 81
s = sqrt(81)
s = 9.
The length of the side of the base is of 9 feet.
