Two heavily loaded sixteen-wheeler transport trucks are 1025 kilometers apart, sitting at two rest stops on opposite sides of the same highway. Driver A begins heading down the highway driving at an average speed of 90 kilometers per hour. Exactly one hour later, Driver B starts down the highway toward Driver A, maintaining an average speed of 80 kilometers per hour. How many kilometers farther than Driver B, will Driver A have driven when they meet and pass each other on the highway?  Choose the correct choice:
A) 90 B) 130 C) 150 D) 320 E) 145
I've been reading the website for a while and I'm always keen to see different approaches so I would like to share one that works for me:   Short version:   Truck A travels for an hour.   Distance remaining = 1025-90= 
<gadget id="calculator">1025-90</gadget>
<output>935</output>
935k   Ratio of speeds 9:8 -&gt; 935/17= 55   Truck A = 90 + 55*9= 
<gadget id="calculator">90 + 55*9</gadget>
<output>585</output>
585   Truck B= 55*8= 
<gadget id="calculator">55*8</gadget>
<output>440</output>
440   Delta= 145km   Answer 145
<result>E</result>
