Sarah walker 3 miles in 45 minutes. What is her average minutes per mile

0.067 mi/min

Step-by-step explanation:

Distance = 3 miles

Time = 45 minutes

Average Speed = ?

I think the answer is 15.

Step-by-step explanation:

Just divide 45 from 3 then you will get the results.

step-by-step explanation:

< 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
