After 1 minute,

Thief = 50m

POLICE= 0m

After 2 minutes,

Thief = 100M

Police= 0m

After 3 minutes,

Thief = 150m

Police= 60m

After 4 minutes,

Thief = 200m

Police= 60+65m = 125m

After 5 minutes,

Thief = 250m

Police= 125+70m = 195m

After 6 minutes,

Thief = 300m

Police= 195+75m = 270m

After 7 minutes,

Thief = 350m

Police= 270+80m = 350m
