Kim can cycle 30 km/h faster than she can run. If the speed at which she can run is X, the speed at which she can cycle is X + 30.

She spends 48 minutes running and 48/3 = 16 minutes cycling. The total distance covered is 60 km.

Distance = speed*time

=> 60 = X*(48/60) + (X + 30)*(16/60)

=> 3600 = 48X + 16X + 480

=> 60X = 3120

=> X = 52

**The speed at which Kim can run is 52 km/h.**
