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?
a 10.2 ft
b 3.08 ft
c 3.08 cm
d 19.25 ft
e 19.25 cm
To find the length of the actual stock car, we can set up a proportion using the given scale:
1 cm / 2.5 ft = 7.7 cm / x ft
Cross-multiplying, we get:
1 cm * x ft = 7.7 cm * 2.5 ft
x ft = (7.7 cm * 2.5 ft) / 1 cm
x ft = 19.25 ft
Therefore, the length of the actual stock car is 19.25 ft.
The answer is (d) 19.25 ft.
