Find the distance between the cities. assume that earth is a sphere of radius 4000 miles and that the cities are on the same longitude (one city is due north of the other). (round your answer to one decimal place.)

city latitude
dallas, texas 32° 47' 39'' n.
omaha, nebraska 41° 15' 50'' n.

870.11 miles ( approx )

Step-by-step explanation:

The difference between the latitudes of the cities = 41° 15' 50'' N - 32° 47' 39''

=  

=

=      

=      

=

Also, the radius of the earth = 4000 miles

Hence, the distance between the cities

e^-kt = n/n0 = 0.79  

-kt = ln 0.79  

t = - ln 0.79/0.0001  

= 2357 years
