A bus run at 100 km/hr top speed. It can carry a maximum of 6 persons. If speed of bus decreases in fixed proportion with increase in number of person, find speed when three person are traveling in bus.

• bus still can run with the top speed of 100kmph,since speed decreases with increase in no. of persons,not with decrease of passengers,so it can go upto 100kmph.

• Exact ratio of decrease with increase in number of person is not given, so required speed can not be calculated correctly.
