Mr. L Driving to Work
Practice Problem
1.
Mr. Lehmann was driving to work
this morning. Before coming to HMS he drove 300 meters in 40 seconds to Dunkin'
Donuts for his morning coffee and plain bagel with cream cheese toasted. He
stayed at Dunkin' Donuts for 3 minutes. He then proceeded toward the highway
400 meters away. This took 1 minute. He then got on the highway for 5 minutes
traveling a distance of 9 kilometers. All of a sudden Mr. Lehmann was stuck
behind an oil truck, an 18 wheeler, and a little old lady for 8 minutes and the
last 4 highway kilometers until the Willington exit. Since he was late he
floored it and he traveled 3 kilometers in 1 minute to arrive at HMS.
Directions:
Create a distance/time graph that graphs
the story portrayed above.
Solution:
|
Time (X) |
Distance (Y) |
|
40 seconds |
300 meters |
|
40+180 = 220 seconds |
300+0 meters = 300 meters |
|
40+180+60 = 280 seconds |
300+0+400 = 700 meters |
|
40+180+60+300 = 580 seconds |
300+0+400+9000 = 9700 meters |
|
40+180 +60 +300+480 = 1060 seconds |
300+0+400+9000+4000 = 13700meters |
|
40+180+60+300+480+60 = 1120 seconds |
300+0+400+9000+4000+3000 = 16700 meters |
