Question 668420: If a witch flies at 16 miles per hour and it takes her a half hour to get there, how long will it take to fly home if she travels 24 miles per hour? Found 2 solutions by Alan3354, gwendolyn:Answer by Alan3354(69443) (Show Source):
You can put this solution on YOUR website! If a witch flies at 16 miles per hour and it takes her a half hour to get there,
--------
Find the distance d = r*t
-----------------------------
how long will it take to fly home if she travels 24 miles per hour?
d = r*t
t = d/r
You can put this solution on YOUR website! Remember the formula for distance is d=r*t, where d is distance, r is the rate, and t is time.
Let's plug in the rate of the witch (16 mph) and the time it took her (.5 hours) into this equation to find how far she traveled.
d = 16*.5
d = 8
So we know that the witch traveled 8 miles. Her return trip should be the same distance, so we know that her flight home will be 8 miles while travelling 24 mph. We can plug this into the distance formula again to find the time (t) her trip will take:
8 = 24 * t
We divide both sides by 24, and get:
8/24 = t
1/3 = t
So we know that if the witch travels 24 miles per hour home, the journey will take a third of an hour.
