Let assume the distance between point A to point B = x km.

We know, Distance = Speed × Time

⇒ Time = Distance/Speed

The man walked at a speed of 6 km/h from point A to B. Then, he would take time = x/6 hours.

And he came back from point B to point A at 8 km/h. Then, he would take time = x/8 hours.

∴The ratio between the time taken by him in walking from point A to B to point B to A

= (x/6) : (x/8) = 4 : 3
