QUESTION

Asif and All are two friends who love exploring new places by going on road trips. They are planning their next adventure and have mapped out some key destinations they want to visit.

Asif plans to visit four cities on her road trip: Lahore, Islamabad, Peshawar, and Karachi. The distances $($in kilometers$)$ between these cities are as follows: Lahore to Islamabad $(375km).$ Islamabad to Peshawar $(190km),$ Peshawar to Karachi $(1300km),$ and Karachi to Lahore $(1100km).$

Ali, on the other hand, has a slightly different route planned: Karachi to Quetta $(850km).$ Quetta to Lahore $(630km),$ Lahore to Multan $(345km),$ and Multan to Islamabad $(560km).$

A$-$ Using Norm$-1,$ What is the total distance difference between Asif's and Ali's road trip itineraries?

B$-$ Using the Norm$-$II$,$ what is the direct distance difference between Asif's and Ali's road trip itineraries?

C$-$ Using the Minkowski distance with $q=3,$ what is the overall distance difference between Asif's and Ali's road trip itineraries?

D$.$ Using the Supremum distance, what is the maximum distance difference between any single city pair $($either common or unique$)$ in Asif's and Ali's road trip itineraries?
