Step-by-step Solution
To determine which options are equivalent to 450 minutes, we first need to convert 450 minutes into other time units.
1. **Convert 450 minutes to hours and minutes:**
\[
450 \text{ minutes} = 7 \text{ hours} + 30 \text{ minutes} = 7 \frac{1}{2} \text{ hours}
\]
2. **Convert 450 minutes to seconds:**
\[
450 \text{ minutes} \times 60 \text{ seconds/minute} = 27,000 \text{ seconds}
\]
Now, let's evaluate each option:
(A) **2,700 seconds**
\[
2,700 \text{ seconds} = \frac{2,700}{60} \text{ minutes} = 45 \text{ minutes} \quad \text{(not equivalent)}
\]
(B) **27,000 seconds**
\[
27,000 \text{ seconds} = \frac{27,000}{60} \text{ minutes} = 450 \text{ minutes} \quad \text{(equivalent)}
\]
(C) **7 hours 30 minutes**
\[
7 \text{ hours} + 30 \text{ minutes} = 450 \text{ minutes} \quad \text{(equivalent)}
\]
(D) **\( 7 \frac{1}{3} \) hours**
\[
7 \frac{1}{3} \text{ hours} = 7 \text{ hours} + \frac{1}{3} \text{ hour} = 7 \text{ hours} + 20 \text{ minutes} = 440 \text{ minutes} \quad \text{(not equivalent)}
\]
(E) **\( 7 \frac{1}{2} \) hours**
\[
7 \frac{1}{2} \text{ hours} = 7 \text{ hours} + 30 \text{ minutes} = 450 \text{ minutes} \quad \text{(equivalent)}
\]
Thus, the options that are equivalent to 450 minutes are:
- (B) 27,000 seconds
- (C) 7 hours 30 minutes
- (E) \( 7 \frac{1}{2} \) hours
Final answer: **(B), (C), (E)**.
