Quizplus · Accepted Answer

Given that 11 inches is approximately the same length as 33 centimeters, we can deduce that 1 inch is approximately equal to 3 centimeters (33 cm / 11 in = 3 cm/in). Therefore, the mathematical model relating centimeters (y) to inches (x) is y = 3x. Using this model, 60 inches is equal to 180 centimeters (60 * 3 = 180), and 70 inches is equal to 210 centimeters (70 * 3 = 210).
