Clearly, the two will meet when they are 726 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 726 m apart, they take (100/825 * 726/1000) hrs= (242/2750 * 60)= 
<gadget id="calculator">(242/2750 * 60)</gadget>
<output>132/25 = around 5.28</output>
