An auto race consists of 8 laps. A driver completes the first 3 laps at an average speed of 170 miles per hour and the remaining laps at an average speed of 195 miles per hour. Let represent the length of one lap. Find the time in terms of that it takes the driver to complete the race. Enter the expression in simplest form.

$32,660

step-by-step explanation:

three-fourths of an hour

36÷48=0.75

0.75=

your answer is d 2,500

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
