Answer:
150 m
Step-by-step explanation:
So the scale of the model is 1 cm = 5 m, and the model is 30 cm long. We can set this up as two fractions, then cross-multiply, like so:
1 cm/30 cm = 5 m/x m
1 * x = x
30 * 5 = 150
Now, set the two products equal to each other. Normally we'd have to simplify, but x is already on its own, so we have our answer:
x = 150 m
