We have the distance Anna walks, which is 9 5/8 miles and the time she takes to walk that far is 2 3/4 hours. Velocity is defined as distance over time:
Therefore we can calcuate her velocity which is speed. We change the numbers to fractions
1st Avenue would be more difficult because it’s rise and run is for every one foot forward it is 3 feet up. Meanwhile avenue 16th would start at (3,1) and the rise and run would be for every 3 feet it would go up 1 foot.
