<PRE><B>Question 988415</B>
Jack and john are both traveling for a family reunion. Jack leaves an hour and a half later. John travels at an average speed of 65 mph. Jack travels at an average speed of 70 mph. How long will it take jack to reach john? 
---------
Jack DATA: 
rate = 70 mph ; time = t-(3/2) hrs ; distance = r*t = 70(t-(3/2)) miles
-----------------
John DATA:
rate = 65 mph ; time = t hrs ; distance = r*t = 65t miles
---------------
Equation:
dist = dist
70t - 105 = 65t
5t = 105
t = 21 hrs
-----------------
t - (3/2) = 19.5 hrs (Jack&#39;s time)
