Question

If a man travels 65 km in 3 days by walking 7 1/2 hours a day,in how many days will he travel 156 km by walking 8 hours a day?​

Answer 1

Answer:

6.75 days

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

Answer 2

gud night!!

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
