Solution

Distance travelled by Dinesh = AB + BC = (7.5 + 12.7) km

Therefore, Dinesh travelled 20.2 km.

Distance travelled by Ayub = AD + DC = (9.3 + 11.8) km

Therefore, Ayub travelled 21.1 km.

Hence, Ayub travelled more distance.

Difference = (21.1 − 20.2) km

Therefore, Ayub travelled 0.9 km more than Dinesh.
