Two trains are traveling on parallel tracks in the same direction. The faster train travels at 130 miles per hour, while the slower train travels at 100 miles per hour. At 2 o’clock the faster train is 25 miles behind the slower one. How far apart are the two trains at 5 o'clock?	Select the correct option:
A) 60 miles  B) 80 miles  C) 90 miles  D) 65 miles  E) 400 miles
Answer = D. 65 miles   Relational speed = 130 - 100= 
<gadget id="calculator">130 - 100</gadget>
<output>30</output>
30 miles per hour   In 3 hours, difference= 30 * 3= 
<gadget id="calculator">30 * 3</gadget>
<output>90</output>
90 miles   Fast train trailing 25 miles, so effective difference= 90 - 25= 
<gadget id="calculator">90 - 25</gadget>
<output>65</output>
65 miles
<result>D</result>
