Answer:
The distance from the North Pole to the equator is  m.
m.
Explanation:
Circumference of Earth = 40,000 km    ......................(1)
Distance from the North Pole to the Equator is =  1/4th of the Circumference of Earth  ......................  (2)
Let Distance from the North Pole to the Equator be  d ,
the equation formed will be ,
d = 1/4 * Circumference of Earth       ........(3)......... ( from equation 1 )
put the value of Circumference of Earth in equation (3),
d = 1/4 * 40,000  km
d = 10,000 km
converting km to m ,
d = 10,000 *  m
 m
d =  1 *  m
 m
The distance from the North Pole to the equator is  m.
m.
