Find the distance along an arc on the surface of the earth that subtends a central angle of 1 minutes (1 minute = 1/60 degree).
-Dominant- [34]

Answer:

1.152 miles

Explanation:

Given: central angle = 1 minute = (\frac{1}{60}) ^{o}

           radius of the earth = 3960 miles

The length of an arc = \frac{\alpha }{360^{o} } 2\pir

where: \alpha is the central angle, and r is the radius.

Thus,

Distance along the arc = \frac{\alpha }{360^{o} } 2\pir

Distance along the arc = \frac{(\frac{1}{60}) ^{o}  }{360^{o} } x 2 x \frac{22}{7} x 3960

                                      = \frac{(\frac{1}{60}) ^{o}  }{360^{o} } x 24891.4286

                                      = 1.1524

The required distance along an arc is 1.152 miles.
