- The person travels a distance of 20 km.

- At 5 km/h, this journey takes 4 hours (20 / 5 = 4).

- The time at 8 km/h is 2.5 hours (20 / 8 = 2.5).

- The usual time (T) is calculated as 4 hours minus 40 minutes (or 2/3 hours), equating to 3.33 hours.

- The time at 8 km/h (2.5 hours) is 0.83 hours less than the usual time (3.33 hours).

- Convert 0.83 hours to minutes: 0.83 * 60 = 50 minutes.

- Correct answer: Option 4, 50 minutes.
