Explanation:

Time            distance

1 hour             20 km

2 hour            30  km

3 hour             40 km

4 hour             50 km

then

average speed  = $\frac{\text{total distance}}{\text{total time taken}}$

total distance = 20+30+40+50 = 140 km

total time = 1+2+3+4 = 10 hours

then

average speed = $\frac{140}{10}$

average speed = 14 km/h
