Question

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

Answer 1

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

Answer 2

Answer:

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.
