Alan works 6 miles away from the apartment and rollerblades from his work place to t he apartment and a constant rate of 7 miles per hour, soren works 8 miles away from the apartment and bikes from his workplace to the apartment at a constant rate of 12 miles per hour how much time, in hours do alan and soren have to travel to be the same distance from their apartment

Step-by-step explanation:

        Let d = distance from apartment

Then 6 - d = distance travelled by Alan

 and 8 - d = distance travelled by Soren

They will each be on the road for the same time.

Distance = speed × time

Calculate the travel times

Alan's distance = (6 - 3.2) mi = 2.8 mi

Soren's distance = (8 - 3.2) mi = 4.8 mi

< 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

hi there!

the answer to this question is d: 35

step-by-step explanation:

5 to the power of 2 is 25
