russia length?

when i see a map of russia it seems huge yet the truth is the "fat" part of the sphere is longer length than around the thin part of the sphere called north.
so we know our planet spins and that defines a real axis and between the edges of the axis is the real equator equal between the axis of spin.
if a helicopter leaves from cairo egypt and travels to SHANGHAI at rate speed 100 kilometers per hour  over 91 hours.
[not the coast by hong kong bad example because south of shanghai need shanghai by 30 north at 31 north similar to cairo]
shanghai to katmandu is 3910km.+5230 to cairo 9140 km
while from the coast of baltic even slightly WEST in saint perterbeg- to magadan russia less  length
even west a bit 30e instead of 31e still coastal sp 1490 km+2200km+3350km to coast magadan russia only 7000 km is 59n so like sp but 150e since it is top of sphere less length
the same helicopter would reach 150 degrees east in only 70 hours! and the one from cairo is 20 hours away from shanghai so i wish a map would show the length as if a straight line north from baltic coast and cairo at 30 east and the length shows reach coast of pacific in only 70 hours 7000 km in contrast to near equator 30n stilll far from shanghai despite number 121 e farther than 150e.
details
sp 60n 30e like magadan russia
cairo 30 north 31e
since 30 north near equator so circumference greater both total and per degree of arc.
cairo to hk is not comparable through  new delhi 4440 kilometer south not east
and nd to hong kong as coast curves south and west 3760km so total 8200km. by 30 degrees n in contrats further north should be less from north of cairo and e
5774 but not straight east
oops shanghai is 31n! not hk and 121.
