Answer 2

Question:-

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

Solution:-

Given:

A man walks per day= 7. 1/2 hours.

=) 15/2

=) 7.5hrs

So,

He walks in 3 days = (3 × 7.5)hrs.

=) 22.5hrs.

He travelled 65km in these 22.5 hours

Therefore,

We know that, speed = distance/time

Speed= 65/22.5

Speed= 2.88km/hr.

Speed of the man will remain same,

Time= Distance/Speed

Time= 156/2.88

Time= 54 hours

Man walks everyday 8 hours for 54 hours

=) 54/8

=) 6.75 days

Hope it helps ☺️
