Problema Solution
The time it takes you to get to campus varies inversely as your driving speed. Averaging 20 miles per hour in bad traffic, it takes you 1.5 hours to get to campus. How long would the trip take averaging 50 miles per hour?
Answer provided by our tutors
y varies inversely with x if there is a constant k such that: xy = k.
Let 't' represent the time needed for the trip when traveling with average speed of 50 mph.
20*1.5 = 50*t

........
t = 3/5 hr
t = 0.6 hr
t = 0.6*60 min
t = 36 min
The trip would take 36 minutes.
