Question

If a stock car model is built to the scale of 1 cm : 2.5 ft and the model measures 7.7 cm in length, what will be the length of the actual stock car?

Answer 1

The answer would be 19.25 ft because 1cm x 2.5 = 2.5 ft so you will have to do the same to 7.7 cm : 7.7cm x 2.5 = 19.25 ft.

Answer 2

Length of model in actual size is 19.25 feet

Given that;

Scale factor = 1 cm : 2.5 Ft

Length of model in scale factor = 7.7 cm

Find:

Length of model in actual size

Computation:

Length of model in actual size = Length of model in scale factor × Scale factor

Length of model in actual size = 7.7 × 2.5

Length of model in actual size = 19.25 feet
