You would have to use an equation. The equation should be 12n+16n=1.5 When you found your answer, you should then use that decimal amount to "times" one hour to get the time. I am pretty sure that this is correct.
Megan and Kate will be 1.5 miles apart in approximately 3.21 minutes. This is determined by their combined riding speed of 28 mph and the distance formula. By calculating the time using the given speeds, we can find how long it takes for them to be that far apart.
