Question 79992: Alex drove 500 miles in 15 days.
At the same rate, how long would it take Alex to drive 5,000 miles?
Answer by sofiyacherni(99)   (Show Source):
You can put this solution on YOUR website! there's two ways to solve this one
logic: if it took 15 days to drive 500 miles then it would take 10 times as much to drive a distance ten times further at the same speed, since 5000 is ten times more than 500, meaning 500(10)=5000
so all you have to do is multiply the number of days it took to drive 500 miles by ten
15(10)=150
math: i always do these ratio kind of problems this way (it would only apply if the speed is the same)
it took 15 days to drive 500
then it would take x to drive 5000
i write then down like this
15 --- 500
x --- 5000
then i multiply across
15(5000)=500x
divide both sides by 500, then you get
15(5000)/500=x
x=150
