With fractions its very easy to get 1 as a whole numer (Which is what were trying to find. ONE miles o we know how much is per hour (one hour)). All you need to do is multiply the 2/3 hour by 3/2. The numers switched. You do this with both variables, the 3/5 miles and the 2/3 hour. After this the hour variable should have turned into a 1if done correctly. Then we multilly the milesvariable by 3/2. when done correctly we get the answer of 69/10miles.
After you've done this, you then know your answer. every 1hour Izzy runs 69/10miles.
Another way of saying this is Izzyruns6.9milesanhour or 6.9mph.
