Hi

D = r*t, In  2, 3, 4 distances are the same and questions are done similarly

 2. 8kmph*t = 5kmph*(3.25hr-t)  

solve for t 

    13kmpht = 5kmph*3.25hr

         t = 5*3.25/13kmph 

         t = 1.25hr     8kmph*1.25hr = 10km.  Total distance walked = 20km

5.   18*x = 16*(x+2) where x is the number of days

solve for x

   18x = 16x+ 32

     2x = 32

      x = 16 days    18/day*16days = 288 sweets

CHECKING our Answer

   288 = 16/day* 18days = 288
