A man takes 6 houus 35 minutes in walking to a certain place and riding back.He would take 2 hours less by riding both ways.What would be the time he would take to walk both ways
Let riding time be R and walking time W (both one way)
R+W=6h 35m
2R=4h 35m
Double first equation and replace 2R from second equation.
Then solve first equation for 2W.
