The circumference of the earth is 40,000 km. The distance from the
North Pole to the equator is 1/4 of the circumference of the earth, which equals __ m.

The distance from the North Pole to the equator is 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

d =  1 * m

The distance from the North Pole to the equator is m.
