<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) 

t {{{alpha}}}{{{1/x}}}

t ={{{k/x}}}

 A particular vehicle takes 60 minutes to travel a specific distance at an average speed of 65 miles per hour.


60 = {{{k/65}}}

k= 3900

b) determine the time (in minutes) it will take the vehicle to travel the same distance at 50 miles per hour. 

t= 3900/50 

t= 78
