To find the ratios of the different options given, we can express each option in terms of megabytes per second.
- Option A:
-
4 seconds, 14 megabytes \[ \text{Rate} = \frac{14 \text{ MB}}{4 \text{ sec}} = 3.5 \text{ MB/sec} \]
-
2 seconds, 7 megabytes \[ \text{Rate} = \frac{7 \text{ MB}}{2 \text{ sec}} = 3.5 \text{ MB/sec} \]
-
8 megabytes for every 3 seconds: \[ \text{Rate} = \frac{8 \text{ MB}}{3 \text{ sec}} \approx 2.67 \text{ MB/sec} \]
-
7 megabytes for every 2 seconds: \[ \text{Rate} = \frac{7 \text{ MB}}{2 \text{ sec}} = 3.5 \text{ MB/sec} \]
-
14 megabytes for every 2 seconds: \[ \text{Rate} = \frac{14 \text{ MB}}{2 \text{ sec}} = 7 \text{ MB/sec} \]
-
2 megabytes for every 7 seconds: \[ \text{Rate} = \frac{2 \text{ MB}}{7 \text{ sec}} \approx 0.29 \text{ MB/sec} \]
-
Now we can summarize:
- Option A: 3.5 MB/sec
- Option B: 3.5 MB/sec
- Option C: 7 MB/sec
- Option D: 0.29 MB/sec
From the calculations, we can see that:
- Options A and B have the same rate of 3.5 MB/sec,
- Option C has the highest rate of 7 MB/sec,
- Option D has the lowest rate at approximately 0.29 MB/sec.
If you're looking for the best option based on speed or capacity per time, option C (14 megabytes for every 2 seconds) is the highest.
