Tarzan looked at 48 websites in 4 hours. At that rate, how many would he look at in 10 minutes?

48 websites per hour / 4 hours = 12 websites / hour

Since an hour is 60 minutes, we have 12 / websites per 60 minutes = w / 10 minutes
or
12/60 = w/10

Solving the proportion in our calculator above, we get
w = 2
