What is the distance between Warsaw Poland and German border in 1937?

In 1937, the distance between Warsaw, Poland, and the German border varied depending on the specific border crossing point, but it was approximately 100 to 150 kilometers (about 62 to 93 miles) to the west. The closest border area was near the town of Słubice, which was directly across the Oder River from Frankfurt (Oder) in Germany. This distance could be traversed by road or rail, contributing to the significant geopolitical tensions of the era.
