<PRE><B>Question 1031894</B>
The time t (in minutes) that a vehicle can travel varies inversely with the average speed x (in miles per hour) that the vehicle travels. A particular vehicle takes 60 minutes to travel a specific distance at an average speed of 65 miles per hour.
------
t = k/x
-----
Solve for &quot;k&quot;:
60 = k/65
k = 3900
----- 
a) write an equation that gives t as a function of x.
t = 3900/x
----------------- 
b) determine the time (in minutes) it will take the vehicle to travel the same distance at 50 miles per hour.
t = 3900/50 = 78 minutes
----------------------------
