Hi,
a man walking with a speed of 5 km/hr reached his target 5 minutes late. 
if he walks at a speed of 6 km/hr, he reached on time{{{highlight(x)}}}
Note:  D = rt   (distance the same both ways)
Question states*** takes 5min{{{(1/12)hr}}} longer at 5kmph 
 {{{6kmph*t = 5kmph(t+ 1/12)}}}
          t = 5/12 hr     and D = {{{6mph*(5/12)hr = (5/2)mi}}}

and...
 {{{5kmph*(6/12)hr = (5/2)mi}}}
