Question
The time it takes to complete a given trip varies inversely as the speed traveled. If it takes Tim 10 hours tro travel from Cleveland to Albany at 42 mi/h, how long will it take him to make the trip at 60 mi/h?

t = k/v^2
so, tv^2 is constant. Therefore,
10/42^2 = t/60^2
so, tv^2 is constant. Therefore,
10/42^2 = t/60^2
Steve
oops.
10*42^2 = t*60^2
10*42^2 = t*60^2
