 * Copy and compete the table and graph on the previous page to show the relationship between distance and time if the students travled a a rate if 55 miles per hour.//

b Use your table and graph to estimate the total distance traveled after 1 3 170 2 4 1/2 228 3 5 1/4 290

c 1 10 550 2 12 1/3 680 3 15 815 d Look for patterns in the table and graph that help you calculate the distance travled for any given time. Write a rule,using words,tht explains how to calculate the destance travled for any given time.

Add 55 so if you want to figure out 15hr you times 15 so 55x15=815

e Use symbols to write your rule from part D as an equation

You x15 so 55x15 in 15 hrs

1 How could you find the distance traveled after 3 1/4 hours by using the table? The graph? The equation?

On the table you see how much time it took to get ter then divide it by half then by another half and you get your answer.On graph you look at the y axis and see were you wanted to get it by 1/4 then you look at the middle and say its 18 you divide it by 2 and you get your answer. On equation you look at the nmber and divide it by 4.

2 Estimate how much time it took the students to reach each if the following cities in their route: a Richmond, Virginia-about 55miles 1 hour bBaltimore, Maryland-about 3/4 6hours cPhilidelphia, Pennsalvania-about 310 miles from williamsburg. 9 hours and 30 min
