Diameter of circular park = 420 m
radius = d/2 = 210 m
circumference of park = path of jogging = 2pi × r = 2×22/7×210 =1320m
Distance covered in 1 revolution = 1320m
time taken = 4 min = 4×60= 240 sec
speed = 1320/2405.5 m per sec

D=420m
R=210m
circumference=2×22/7×210=1320m
in 4 min ram moves 1320m
in 1 min ram moves 1320/4=330m
speed=330m/min
