Which scales are equivalent to the scale 1cm to 5km? More than one is the right answer

A. 3cm to 15km

B. 1mm to 150km

C. 5cm to 1km

D. 5mm to 2.5km

E. 1mm to 500km

Option A and D.

Step-by-step explanation:

The scale is given 1 centimeter = 5 kilometers

We have to find the equivalent scales from the given options.

A. 3 cm to 15 km

∵ 1 cm to 5 km

∴ 3 cm to 3 * 5 = 15 km

This option is right.

B. 1 mm to 150 km

∵ 1 mm = 0.1 cm

∴ 0.1 cm = 150 km

This is not the correct option

C 5 Cm to 1 km

∵ 1 cm to 5 km

∴ 5 cm = 5 * 5 = 25 km

This option is incorrect.

D. 5 mm to 2.5 km

1 cm = 10 mm

5 mm = 0.5 cm

∵ 0.5 cm = 2.5 km

∴ 1 cm = 2.5 : 0.5 = 5 km

This is the correct option

E. 1 mm to 500 km

10 mm = 1 cm

1 cm to 5000 km

This is not correct

Therefore, Option A and D is equivalent to the scale.

The answer would be A because each side is being multiplied by 3
