Brian runs 6 miles in 44 minutes. At the same rate, how many minutes would he take to run 9 miles?
Whenever we're dealing with problems like these, it helps to set up a ratio. So let's do that!
We can set up a ratio where miles is our numerator, and minutes (time) is our denominator. We get:
We can now cross multiply, which is essentially multiplying in the pattern of an
We will be multiplying the
We can divide both sides by
Sure, we have an
Well, earlier, we defined
This means it will take Brian
