One hour before John started walking from P to Q, a distance of 28 miles, Ann had started walking along the same road from Q to P. Ann walked at a constant speed of 3 miles per hour and John at 2 miles per hour. How many miles had Ann walked when they met?
Choose the correct choice from the following options
A) 6 miles B) 8,4 miles C) 9 miles D) 9,6 miles E) 18 miles
Ann walks from Q to P at a speed of 3 miles/hr for one hour. She covers 3 miles in 1 hour and now distance between John and Ann is   28 - 3=

25 miles.   Ann walks at 3 mph and John at 2 mph so their relative speed is   3+2=

<output>5</output>
5 mph.   They have to cover 25 miles so it will take them  25/5= 
<gadget id="calculator"> 25/5</gadget>
<output>5</output>
5 hours to meet.   In 5 hrs, Ann would have covered 5 hrs * 3 miles per hour= 15 miles.   Adding this to the 3 miles she covered before John, Ann covered a total of 3 + 15= 
<gadget id="calculator">3 + 15</gadget>
<output>18</output>
