Answer:
distance = 994.75 miles
Step-by-step explanation:
given data
City A = 36°6′ = 36° +
= 36.1° = 36.1° ×
= 0.6297 rad
City B = 21°42′ = 21° +
= 21.7° = 21.7° ×
= 0.3785 rad
multiply by π/180 to convert the degree to radian
radius of Earth = 3960 miles
to find out
distance between City A and City B
solution
we first get here central angle between A and B city is
central angle between A and B city = 0.6297 rad - 0.3785 rad
and
now by arc length so we get distance
distance = 3960 miles × (0.6297 rad - 0.3785 rad )
distance = 994.75 miles
