Miguel builds a model airplane with the scale 1in = 6ft . if the model is 9.3 inches long how long was the actual airplane ? answer : 54.2 ft

55.8 ft

Step-by-step explanation:

This seems simpler than it is.

So since it's going from inches to feet, we have to first know the conversion rate of inches to feet which is simple, 12 inches=1 foot. So now we have to figure out how many inches is 6 ft, so 12*6 equals 72. So knowing the scale, we can just do 9.3 *72=669.6. But if we want to know how long the actual airplane was in feet, then we have to do 669.6/12 which equals 55.8

Another way we could do it is by doing 9.3*6. This works because if you multiply something 12 and then divide it by 12, it just becomes 1. But doing this, you can't find the actual airplanes length in inches.
