Step-by-step explanation:
Every day he walks 7.5 hrs
So in three days he walks 7.5×3 =22.5hrs
And he travelled 65km in these 22.5hrs
So the speed = distance/time
= 65/22.5 = 2.88km/hr
Speed of the man will remain same,
So time = distance/speed
= 156/2.88 = 54 hrs
Everyday he walks 8hrs, so for 54 hrs, he has to walk 54/8 = 6.75 days
