Answer the question:
A car travels $$100\,km.$$ The journey takes two hours. The highest speed of the car is $$80\,km/h,$$ and the lowest speed is $$40\,km/h.$$
What is the average speed for the journey ?

Correct option is B. $$50\,km/h$$
we know that

Average speed $$v_{avg}=\dfrac{\text{Total Distance}}{\text{Total Time}}$$

$$v_{avg}=\dfrac{100}{2}=50\text{ km/h}$$

so average speed is 50 km/h.
