To find the unit rate of the computer copying over files, you can calculate the rate of file size copied per minute for each entry in your data.
The unit rate is calculated as follows:
\[ \text{Unit Rate} = \frac{\text{Total File Size (GB)}}{\text{Time (minutes)}} \]
Now let's calculate for each pair of time and total file size:
-
For 2 minutes and 10 GB: \[ \frac{10 \text{ GB}}{2 \text{ min}} = 5 \text{ GB/min} \]
-
For 4 minutes and 20 GB: \[ \frac{20 \text{ GB}}{4 \text{ min}} = 5 \text{ GB/min} \]
-
For 5 minutes and 25 GB: \[ \frac{25 \text{ GB}}{5 \text{ min}} = 5 \text{ GB/min} \]
-
For 6 minutes and 30 GB: \[ \frac{30 \text{ GB}}{6 \text{ min}} = 5 \text{ GB/min} \]
In all cases, the unit rate of the computer copying over files is consistent at 5 GB per minute.
