We have the following:
The first thing is to pass the time from hours to minutes, knowing that 1 hour equals 60 minutes
![6h\cdot(60\min)/(1h)=360\min](https://img.qammunity.org/2023/formulas/mathematics/college/q0347lmvc33qcv7nfgo4mnuljg7ie7tuge.png)
Now, we know that you can see 2 sites in 5 minutes, we calculate the number of sites like this
![360\min \cdot\frac{2\text{sites}}{5\min }=144\text{sites}](https://img.qammunity.org/2023/formulas/mathematics/college/4o1nw2y549n92k0hhc1azi9nlcojhxnrcb.png)
Therefore, in 6 hours you will see a total of 144 sites
