Total distance travelled by Dinesh = AB + BC 

=  7.5km + 12.7km

= 20.2 km 

 Total distance travelled by Ayub = AD + DC 

= 9.3km + 11.8 km

=  21.1 km 

Hence Ayub travelled More distance than Ayub as 21.1 > 20.2

The difference between path travelled by them = 21.1km - 20.2 km 

= 0.9 km.

Hence Ayub travelled 0.9 km more than Dinesh.
