Answer 1

Explanation:

average speed = 40+60÷2

=50 km/ hr

Answer 2

Answer:

The average speed means the speed. So if the distance and time is not given, we take the time in each of the cases to be 1hr. So the total distance is 60+40=100 k m and time is 2hr.

This gives me average speed as 100/2= 50km/hr

Thank you, hope now you get it. Actually you just need to add the two and divide by 2. I have explained why we do so. Thank you
