Question 445646
from point a to point b it takes 55 minutes you are 1/5 into the journey how long have you left to get to point b
-----
You have gone 1/5 th of the way in 55 minutes.  You still have
4/5 of the way to go.  4/5th is 4 times (1/5).  So it will take
you 4(55 minutes) = 220 min = 3hr 40 min to complete the journey.
----
Here's the math using a proportion to show the answer.
----------------
x/(4/5) = 55 min/(1/5)
----------------
x = (4/5)(55/(1/5))
-------
x = 4*55 = 220 minutes = 3 hrs 40 min
