If we look at the chart, it shows that 1 hour is equal to 45 miles. Then, 2 hours is equal to 90 miles and so on. This means that for every hour the distance is 45 miles. Therefore, the distance=45 miles times the number of hours. This is equivalent to d=45h The number 45 is equal to the number of miles and the "h" is equal to the amount of hours. I hope I didnt confuse you in the process of writing this and have a good day!
