The average speed of this student is 8 kilometers per hour.

Step-by-step explanation:

In order to find the answer, you have to use the following formula to calculate the average speed:

S=d/t

S=average speed

d=distance= 4 kilometers

t=time= 30 minutes (you have to express this in terms of hours by dividing this by 60 that is the amount of minutes in an hour=30/60= 0.5 hours

S=4 kilometers/0.5 hours= 8 kilometers per hour

According to this, the answer is that the average speed of this student is 8 kilometers per hour.
