2.4miles   Now since both are walking in opposite directions, add their speeds - 6+5=11m/hr and distance to cover is  25 -2.4= 
<gadget id="calculator"> 25 -2.4</gadget>
<output>22.6</output>
22.6   Time taken= Distance/ Speed = 22.6/11 = 2.05 hrs   Heather will cover = 5*2.4 = 10.2 miles.   Answer 10.2 mile
