We know that the distance to college remains constant.
D = Distance
T = Time to reach college on time

We know that @ 20 km/h John was 10 minutes late
D = 20km/h(T+10)

We know that @ 25 km/h John was 4 minutes late
D = 25km/h(T+4)

Equating the 2 equations

20(T+10) = 25(T+4)
T = 20 Minutes

Use one of those equations to determine distance

20km/h(20+10 min)(1h/60 min) = 10 km
