Question

The question I would like assistance with is posted below.

68. Longitude Longitude is the angular distance (expressed in degrees) East or West Greenwich, England. Arcs of 1° longitude are 110 km apart at the equator, and of the prime meridian, which goes from the North Pole to the South Pole through 68. Longitude Longitude is the angular distance (expressed in degrees) East or Greenwich, England. Arcs of 1° longitude are 110 km apart at the equator, ana therefore 15° arcs subtend 15(110) km, or 1650 km, at the equator. North Pole 15° W 15° E |30이w Equator 1650km Prime meridian South Pole Because Earth rotates 15° per hr, longitude is found by taking the difference between time zones multiplied by 15°. For example, if it is 12 noon where we are (in the United States) and 5 P.M. in Greenwich, we are located at longitude 5(15°), or 75° W. (a) What is the longitude at Greenwich, England? (b) Use time zones to determine the longitude where you live.
