Model the problem with algebra tiles. Then use the model to write an algebraic expression that represents the situation. Isaac g
ave away five balloons. How can you model this situation? The situation can be modeled by algebra tiles with and . The situation can be represented as an algebraic expression as .
If the train travels 744 miles in 3 hours then to determine the unit rate the train is traveling per hour you have to divide the miles by the hours, in this case (744 miles)/(3 hours). The final result concludes as 248 miles per hour.
