Answer:

11.8125°

Step-by-step explanation:

Here r=2/3 km

circumference=2πr=2*22/7*2/3

C=2*22*2/7*3=88/21--------------(1)

Distance traveled in 15 seconds

=15/3600*33=15*33/3600

=11/80 km

distance/C

=11/80 / 88/21

=11/80*21/88

=(11*21)/80*88

=231/7040

SO ANGLE

=360*231/7040

=83160/7040

=11.8125°
