Lionel left his house and walked towards Walt's house, 48 miles away. Two hours later, Walt left his house and ran towards Lionel's house. If Lionel's speed was 2 miles per hour and Walt's 6 miles per hour, how many miles had Lionel walked when he met Walt? Choose the correct choice from the following choices:  A) 12  B) 15  C) 20  D) 24  E) 28
In the first 2 hours Lionel at the rate of 2 miles per hour covered distance=rate*time=2*2= 
<gadget id="calculator">2*2</gadget>
<output>4</output>
4 miles. So, the distance between him and Walt was 48-4= 
<gadget id="calculator">48-4</gadget>
<output>44</output>
44 miles when Walt left his house. Now, their combined rate to cover this distance was 2+6= 
<gadget id="calculator">2+6</gadget>
<output>8</output>
8 miles per hour, hence they will meet (they will cover that distance) in time=distance/rate=44/8= 
<gadget id="calculator">44/8</gadget>
<output>11/2 = around 5.5</output>
5.5 hours. Total time that Lionel was walking is 2+5.5= 
<gadget id="calculator">2+5.5</gadget>
<output>7.5</output>
7.5 hours, which means that he covered in that time interval distance=rate*time=2*7.5= 
<gadget id="calculator">2*7.5</gadget>
<output>15</output>
15 miles.   Answer: 15.
