r=50m
speed=12km/hr
t=20 rounds the field
so,
r-speed÷time taken=50-12÷t=38÷20=19÷10=1 .9.
i hope this answer may be helpful.

Circumfernce of circle = 2*22/7*50
=314.28 (area to be covered in 1 round)
for w0 rounds =314.28×20
=6285.6
S=D/T
Speed= 12×5/18(in metre /sec)
=10/3
Time= distance /speed
6285.6/3.333
=1885.86 sec
