Can someone please help me with this? Timmy can run 1 ⅔ of a mile in ¼ of an hour. What is the unit rate that describes the miles per hour?

6⅔/hr

i'm not sure if this is the answer you need.

< 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
