The time it takes you to get to campus varies inversely as your driving rate.
t = k/r
---
Solve for "k" using "Averaging, 20 miles per hour in terrible traffic, it takes you 1 hr to get to campus."
1 = k/20
k = 20
----
Equation for this problem:
t = 20/r
----
Solve: How long would it take averaging 45 miles per hour?
t = 20/45
t = 4/9 hr. = (4/9)(60 min) = 26 2/3 minutes
