Question 110877
The radius of the earth at the equator is approximately 4000 miles. Suppose a jet flies once around the earth at a speed of 500 miles an hour relative to earth. If the flight path is a negligible height above the equator, give the number of hours of flight.
:
Find the circumference of the earth:
C = 2*pi*4000
C = 25132.74 mi
:
Time = Dist/speed
T = 25132.74/500
T= 50.2655 hrs
