The time it takes you to get to campus varies inversely as your driving speed.
t = k/s
-----
Solve for "k" using "Averaging 20 miles per hour in bad traffic, it takes you 1.5 hours to get to campus."::
1.5 = k/20
k = 30
----
Equation::
t = 30/s
-----
How long would the trip take averaging 50 miles per hour ?
t = 30/50 hrs.
time = (3/5)60 = 36 minutes
