<PRE><B>Question 54881</B>
Sam is on a train traveling south at 34 mph. He spots a second train traveling east at 23mph and records it takes 18 seconds for the 2nd train to pass. How long in feet is the second train?
-------------------
Need to know how far the 2nd train travels in 18 sec.
Distance = rate*time
distance = 23 (mi/hr)(18 sec/3600 sec)=0.115 mi.
Convert to feet:
0.115 mi = 0.115(5280 ft.)=607.2 ft.
Train is 607.2 ft. long
