Answer:
(i)=4-2=2hours , because it is taking 4 hours to cover in 60km per hour and and if we add 20 km speed so that equals to 2 and from 4hours minus 2 we get 2 hours
(ii)=4+2=6hours,if we do with the time they gave us in the question and if we do it with the time we got we get
= 2+2=4hours
I HOPE THIS HELPS
