A model motorcycle has a scale of 0.5 in : 1.3 ft. If the real motorcycle is 10.4 ft long, then how long is the model motorcycle?

Question

i need help with this please i really do

Answer 1

Use a proportion of ratios of corresponding parts in model and real motorcycles:

 

length of model/Length of motorcycle = 0.5 in/1.3ft = x in./10.4 ft   so   x = 10.4(.5/1.3) inches = 4"
