Answer:
C. 3.33
Step-by-step explanation:
Answer: 33.6 min
Step-by-step explanation:
Volume = L*W*H = 9 * 13 * 14 = 1638 in^3
Vol2 = 21 * 25 *35 = 18375 in^3
18375/1638 = 11.2 times bigger, so 3min * 11.2 = 33.6 minutes

Step-by-step explanation:
Answer: Yes; " d/t = r " ;
__________________________
is, in fact, an equivalent equation to: "d = r t" .
___________________________
Explanation:
___________________________
Consider the equation: "d = rt" (which is, " d = r*t ").
We are asked if: " d/t = r " an "equivalent equation" [ to: " d = rt "] .
___________________________
Note that: "d/t = r " is the same as: ↔ "r = d/t ".
So, given: "d = rt" ; let us rewrite the equation, by isolating: "r" on one side of the equation:
_____________________
→ d = r t ; divide EACH SIDE of the equation by "t" ; to isolate "r" on one side of the equation:
__________________________
→ d/t = (r*t) / t ; to get:
→ d/t = r ; so yes; "d/t = r" and: "d = rt" are equivalent equations.
___________________________
Note: In practice, these variables are often used in the formula:
"d = rt" ; or, "distance = rate * time" .
