Final answer:
The equivalent scales to the scale 1 cm to 5 km are 3 cm to 15 km and 5 mm to 2.5 km.
Step-by-step explanation:
The equivalent scales to the scale 1 cm to 5 km are:
- 3 cm to 15 km
- 5 mm to 2.5 km
To determine if a scale is equivalent, we need to compare the ratios of the lengths on both scales. For example, for the scale 1 cm to 5 km, we can compare 1 cm to 500 m (because 5 km is equal to 5000 m). We can also compare 1 cm to 50 mm (because 500 m is equal to 50,000 mm). If the ratios match, the scales are equivalent.
