Equation

Be able to use mixed applications. Example: The school hallway is 190 feet long. If Carlos walks the length of the school hallway 3 times, will he have walked at least 500 feet? How far will he have walked?

Estimate, because an exact number is not needed to compare, unless the comparison is close to the number in the question. 200*3=600. Yes that is close to 500, however we just need to know if he will walk 500 feet or more at this point. The second part of the question ask us to be more specific and find the exact amount. So if we know we added 10 to each number to estimate and we did that 3 times, we can subtract 30 from 600 and we will find Carlos walked 570 feet.
