<PRE><B>Question 209758</B>
I could really use some help solving the following: 
Marsha traveled 400 miles with an average speed of x miles per hour. Find a rational function T(x) that giver her travel time in hours. 
---------------------
time = distance/rate
T(x) = 400 miles/x mph 
T(x) = (400/x)hours
==========================
Cheers,
Stan H.
