You can put this solution on YOUR website! let distance be x
..
to town 64 kph
time taken = x/64 hours
..
back 80 kph
time taken = x/80 hours
..
Total time taken = 1 hour 21 minutes
= 1 (21/60)
=81/60 hours
..

..
..
x= 48
to town time taken = 48/64
=3/4 hours
Balance 36 minutes to return = 0. 6 hours
