Answer:
2H:20m
Step-by-step explanation:
12/4 = 3km journey in fist hour..
and remaining length is 9 but here he wait 10 minutes in every km then we take only 8 km because last 1km is reached the home..
so finally 10*8=80
1 hr +1hr+20mins= 2hr 20 m

In 3hours and 30minutes
prabha89:
4 hours 50 mints
how
3multiply 4 and per km 10min rest is equal to 30
3hours and 30min
10 mints for every kilometer , so total he takes 11 times rest , so 110 mints of rest i.e 1 hour 50 mints.... so 3 hours+ 1 hour 50 mints , so 4 hours 50 mints
i dont know exactly , but i thought like that
ok
i also don't know exactly
yeah
