Question

If ram has 5 apples and distance between ram and sham is 5 km then calculate the distance between sun and moon

Answer 1

Aristarchus around 270 BC derived the Moon's distance from the duration of a lunar eclipse (Hipparchus later found an independent method). It was commonly accepted in those days that the Earth was a sphere (although its size was only calculated a few years later, by Eratosthenes )
