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   38 - 3= 
<gadget id="calculator">  38 - 3</gadget>
<output>35</output>
35 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 35 miles so it will take them  35/5= 
<gadget id="calculator"> 35/5</gadget>
<output>7</output>
7 hours to meet.   In 7 hrs, Ann would have covered 7 hrs * 3 miles per hour= 21 miles.   Adding this to the 3 miles she covered before John, Ann covered a total of 3 + 21= 
<gadget id="calculator">3 + 21</gadget>
<output>24</output>
