Well we know that 1 centimeter = 50 miles, so 2 centimeters = 100 miles. Now we have to find what 0.4 centimeters equals. To do this we must find 40% of 50. We simply multiply 0.4 and 50 to get our answer. 0.4 × 50 = 20. So we add 20 to 100. 20 + 100 = 120 So 2.4 centimeters = 120 miles. Hope I helped!
