After 1st week, subscribers = 0

After 2nd week, subscribers = 0

After 3rd week, subscribers = 1

After 4th week, subscribers = 1x4 = 4

After 5th week, subscribers = 4x4 = 4^2 = 4^(5-3) 

After 6th week, subscribers = 4x4x4= 4^3=4^(6-3) 

Therefore, after 12th week, subscribers =

 4^(12-3) = 4^9 = 262144

Speed=Distance/time

Here,

distance=15m

time=1sec

speed=15/1=15m/sec

Distance=Speed*time

time=15min=15*60sec=900sec

Distance travelled in 15 min=15*900=13,500m

=13500/1000 km=13.5Km
