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!
