Question

If a man travels 65 km in 3 days by walking 15/2 km hours a day , in how many days will he travel 156 km by walking 8 hours a day?

Answer 1

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
