A) 5.29 min
B) 5.28 min
C) 4.08 min
D) 9.28 min
E) 5.988 min
Clearly, the two will meet when they are 561 m apart.   To be (4.5 + 3.75)= 
<gadget id="calculator">(4.5 + 3.75)</gadget>
<output>8.25</output>
8.25 km apart, they take 1 hour.   To be 561 m apart, they take (100/825 * 561/1000) hrs= (561/8250 * 60)= 
<gadget id="calculator">(561/8250 * 60)</gadget>
<output>102/25 = around 4.08</output>
4.08 min.   Answer: 4.08 min
<result>C</result>
