Question:

A bus covers first 200 km of a journey in 4 hours and the next 600 km in 6 hours. What is the average speed of the bus for the whole journey?

Options:

100 km/h

90 km/h

60 km/h

80 km/h

Correct Answer:

80 km/h

Explanation:

Average speed = $\frac{Total\; Distance }{Total \; Time }$

Total distance = 200 + 600 = 800 km

Total Time = 4 + 6 = 10 hours

Average speed = $\frac{800}{10}$

= 80 km/h
