Let x = amount of time the Arlen family must catch up to overtake the Harris family

In principle, the Harris and the Arlen family should cover the same distance. Since distance is speed x time,

45 (6+y) = 58y

270 + 45y = 58y

58y - 45y = 270

y = 270 ÷ 13

y= 20.77min

Angle DEC and Angle DEH

=============================================================

Explanation:

I recommend opening your favorite paint program, and using different colors to mark on the drawing as I have done below (see attached image). Note how angle DEC is in red and angle DEH is in blue. The two angles are adjacent, meaning they share the same ray (in this case, ray ED) and they form a straight angle.

Because they form a straight angle, or straight line, this means the two angles are supplementary. Supplementary angles always add to 180.
