Hello! your answer is:

6 miles per hour

explanation:

Distance traveled, d = 2 1/2 miles = 5 / 2 miles

time taken, t = 5 / 12 hour

Speed is defined as the ratio of distance traveled to the time taken.

speed = 6 miles per hour

Thus, the unit rate of Chen is 6 miles per hour.

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30
