Question 1
A map has a scale of 1 to 50000. If two towns are 4 centimetres apart on the map, what is the actual distance between them in kilometres?
Show answer
Answer: 2
Multiplying 4 centimetres by 50000 gives 200000 centimetres. Since there are 100000 centimetres in a kilometre, dividing by 100000 results in 2 kilometres.

Question 2
Which statement correctly describes the function of a scale drawing?
- A) It maintains the original shape by using a fixed ratio
- B) It increases the object size by a factor of ten units
- C) It changes the interior angles to fit the paper space
- D) It represents lengths using a random scaling constant
Show answer
Answer: It maintains the original shape by using a fixed ratio
A scale drawing uses a fixed ratio to ensure that all lengths are proportional, which preserves the original shape. Other options are incorrect because angles must remain unchanged and the ratio must be consistent.

Question 3
A model car is built to a scale of 1 to 24. If the actual car is 4.8 metres long, how many centimetres long is the model?
Show answer
Answer: 20
The actual car is 480 centimetres long. Dividing 480 by 24 gives a model length of 20 centimetres.
