Xiao Shanwa is going to participate in the county sports meeting. If he walks 4 kilometers per hour, he will be 0.5 kilometers away from the county seat after the scheduled time. If he walks five kilometers an hour, Assuming that the predetermined time is x hours,

The distance from the school to the county seat is:

4t+0.5

This distance is also equal to:

5 (ton-0.5) (km)

So:

4t + 0.5 = 5(t - 0.5)

4t + 0.5 = 5t - 2.5

T = 3 (hours)

Therefore, the distance from the school to the county seat is:

4t+0.5 =12.5km.
