Question

A model of a park was built on a scale of 1.5 cm to 50m. If the distance between two trees in the park is 150m, what is this distance on the model? Explain what you did.

A. 0.5 cm
B. 4.5 cm
C. 75 cm
D. 225 cm

Answer 1

we know that

[scale]=[measure in model park]/[measure in actual park]
[measure in model park]=[scale]*[measure in actual park]
scale=1.5 cm/50 m

If the distance between two trees in the park is 150 m
so
[measure in actual park]=150 m

[measure in model park]=[1.5/50]*[150]------> 4.5 cm

the answer is the option
B. 4.5 cm
