Question

Express 1 degree angular distance in kilometres.

ICSE Class 9 Total Geography Ch 2:Geographic Grid- Latitudes and Longitudes

Answer 1

1 DEGREE ANGULAR DISTANCE IN KILOMETERS IS 111.2KMS.

Answer 2

Answer:

The "circumference" of the equator is “40,000 kilometres”.1 degree angular distance in kilometres is “111.2km or 69 miles”. We got this value by dividing 40,000 by 360 degrees as the earth is a sphere, and the total degrees a sphere or a circle has are 360 degrees. Thus each degree among these 360 degrees represents a total of 111.2 km which totals up to roughly 40,032 km - the length of the equator.
