Question:

A man completes 30 km of a journey at 6 km/h and the remaining 40 km of the journey in 5 h. His average speed for the whole journey is :

Options:

7 km/h

15 km/h

20 km/h

12 km/h

Correct Answer:

Explanation:

Total distance = 30 + 40 = 70 km

Total time = 30/6 + 5= 5 + 5 = 10 hours

Average speed = Total distance / Total time

= 70 / 10

= 7 km/h

The correct answer is option (1) : 7 km/h
