At What Speed (km/h) the Bus must Travel in Order to Complete the Journey 9 h ?
Answer: (2) 40 km/h
The speed of the bus = 60 km/h
Time taken by bus to covered the journey = 6 h
The distance covered by bus = 60 x 6
= 360 km
Now, The speed of the bus to cover the same distance in 9 h = 360/9
= 40 km/h
hence, the answer is (2) 40 km/h.
