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.

150 km/h

Explanation:

It is given that,

Speed of a bus is 100 km/h and it can carry a maximum of 6 persons.

If speed of bus decreases in fixed proportion with increase in number of person, then we need to find the speed when 3 person are traveling in bus.

6 person = 100 km/h

1 person = (100/6) km/h

Ans

3 person =

Net speed = 100 km/h + 50 km/h = 150 km/h

Hence, if the required speed is 150 km/h.
