<PRE><B>Question 288624</B>
Bob travels on a train at 80 mph with a 30 minute layover halfway through
 the 156 mile trip at 8:00a.m. or by car traveling 55 mph at 8:00a.m. traveling 156 miles. 
Which method of transportation train or car allows Bob to arrive sooner at his destination?
:
Write a time equation for each; time = dist/speed
:
Train: {{{156/80}}} + .5 = 2.45 hrs
Car: {{{156/55}}} = 2.84 hrs
:
Obviously, the train wins!</PRE>
