Answer:
280/4 = 70 miles per hour. Next, take the unit rate and multiply it by the number of hours you are trying to find. In this case, you are trying to find 6 hours and 30 minutes, but this can also be rewritten as 6.5, since 30 minutes is half an hour. So, in 6.5 hours, the car can go 455 miles
To get the previous population you would have to multiply 9,300 by 38% (.38) and then add it to 9,300, or you can also multiply it by 138% (1.38) and still get the same answer but this step is only a one step the first is a two step process
