Draw a linear scale

Question

Draw a linear scale of R F 1:25000000 and measure it's distance in kms and meterss

Answer 1

RF 1:25,000,000 means that 1 unit on the map represents 25,000,000 of the same units on the ground. If you use centimeters, 1 cm on the map equals 25,000,000 cm on the ground, which is 250 km or 250,000 m. To draw a linear (bar) scale, draw a 4 cm line and mark it every 1 cm; label the marks 0, 250, 500, 750, and 1,000 km. You can put 0, 250,000, 500,000, 750,000, and 1,000,000 m beneath the same marks. For any two points separated by d centimeters on the map, multiply d by 250 to find kilometers, or by 250,000 to find meters.
