Answer:
Option A and D.
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.
