"Write a proportion for the problem & solve: A plan flew 600 miles in 2 hours. How many miles did it fly in 7 hours at the same rate of speed?"

600 miles / 2 hours = x miles / 7 hours {this is the proportion}
2x = 7(600) {cross-multiplied}
2x = 4200 {multiplied 7 by 600}
x = 2100 miles {divided both sides by 2}
