A map has scale 1:25,000. Two landmarks are 6 centimetres apart on the map. What is their real distance?

Erklärung

Six map centimetres represent 6 times 25,000, or 150,000 real centimetres, which is 1.5 kilometres. The 150-kilometre choice keeps the digits but converts centimetres to kilometres incorrectly by a factor of one hundred.
