Answer:
30°
Step-by-step explanation:
If chord AB subtends two arcs with measures in the ratio of 1:5, then the measure of minor arc is x and the measure of major arc is 5x. Thus,

Thus, the measure of the angle AOB is 60°. Consider isosceles triangle AOB (because AO=BO=radius of the circle). The angles adjacent to the base AB are congruent, thus

Since line CD is tangent to the circle,

Hence,

WORK:
61 + 53 = 114
798 ÷ 114 = 7
ANSWER:
They will be 798 miles apart in 7 hours.
