<PRE><B>Question 165248</B>
This rider/walker rode @ 45 mph. for x hours (45x) then walked @ 6 mph. for 
(2-x) hours.
-----------------------------------------------------------
45x+6(2-x)=25
45x+12-6x=25
39x=25-12
39x=13
x=13/39
x=.333 hours for the 45 mph trip.
45*.333=15 miles is the motorcycle trip distance.
Proof:
45*.333+6(2-.333)=25
15+6(1.667)=25
15+10=25
25=25</PRE>
