Acar travels at an average speed of 48 miles per hour. how long does it take to travel 180miles?

3 hours and 45 minutes

Step-by-step explanation:

Divide 180 by 48, and you get 3.75, which is 3 hours and 45 minutes

< 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
