Darcy lives 1.5 miles from work. She can walk to work at a constant rate of 3 miles per hour, or she can ride the train to work at a constant rate of 20 miles per hour. If she rides the train, there is an additional x minutes spent walking to the nearest train station, waiting for the train, and walking from the final train station to her work. If it takes Darcy a total of 20 more minutes to commute to work by walking than it takes her to commute to work by riding the train, what is the value of x?
Select the correct option
A) 5.5	B) 15	C) 25.5	D) 30	E) 60
The time it takes Darcy to walk to work is (1.5/3)*60= 
<gadget id="calculator">(1.5/3)*60</gadget>
<output>30</output>
30 minutes   The time it takes Darcy to take the train is (1.5/20)*60 + x= 4.5 + x minutes   It takes 15 minutes longer to walk, so 30 = 4.5 + x + 20   x=5.5 minutes   5.5nswer: 5.5
