### Presentation Transcript

1. Distance = (Rate)(Time) Distances are Equal RT = RT Sum of Distances RT + RT = D Unequal Distances RT + D = RT

2. p. 341 Distances are Equal RT = RT On Tuesday the express train made the trip in 12 hours. On Wednesday the freight train made the same trip in 16 hours. Find the rate of each train if the rate of the freight train was 15 km per hour less than the rate of the express train.

3. Distances are Equal RT = RT Candide and Pangloss walked to the site of the disaster in 9 hours. The next morning they jogged back home in 3 hours. How far did they jog if they jogged 4 miles per hour faster than they walked?

4. p. 354 Sum of Distances = A number RT + RT = D A southbound bus left Fort Walton Beach at 9 a.m. Two hours later a northbound bus left the same station. If the buses traveled at the same rate and were 352 kilometers apart at 2 p.m., find the rate of the buses.

5. Sum of Distances = A number RT + RT = D The ships were 400 miles apart at midnight and were headed toward each other. If they collided head-on at 8 a.m., find the speed of both ships if one was 20 miles per hour faster than the other. 400

6. p. 374 Unequal Distances RT + D = RT At 8 p.m. Achilles left camp and headed south at 20 kilometers per hour. At 10 p.m. Patroclos headed south from the same camp. If Patroclos was 50 kilometers ahead by 3 a.m., what was his speed? Ach 50 Pat

7. Unequal Distances RT + D = RT Helen has a 4-kilometer head start on Paris. How long will it take Paris to catch Helen if Helen travels at 6 kilometers per hour and Paris travels at 8 kilometers per hour?
