Sam is building a model of an antique car. The scale of his model to the actual car is 1:10. His model is 181/2 inches long.how long is the actual car ?
If his model car is 181/2 inches and its relation to the actual car is 1:10, then the actual car size is 10 times 181/2 which is 1810/20 inches. I hope it'll help :)
