1. A crazy dog runs 300 meters east, changes his mind and then runs 200 meters west. He then changes his mind again and runs 500 meterg east. This entire trip takes 2 minutes.
a) What is the total distance traveled?
b) What is the total displacement?
c) What was the dog's average speed?
d) What was the dog's average velooity?
2. A. long distance running is running the $10000 \mathrm{~m}$ race. He runs the first $2000 \mathrm{~m}$ in 5 minutes, the next $5000 \mathrm{~m}$ in 14 minutes and the final 3000 meters in 7 minutes. What was the runnar's
Answer
\(\boxed{1000}\) meters is the total distance traveled by the dog.
Step 1 ：Let the distances the dog ran be represented as distance1, distance2, and distance3 respectively. So, distance1 = 300 meters, distance2 = 200 meters, and distance3 = 500 meters.
Step 2 ：The total distance traveled by the dog can be calculated by adding up all the distances the dog ran, regardless of the direction. So, total_distance = distance1 + distance2 + distance3 = 300 meters + 200 meters + 500 meters = 1000 meters.
Step 3 ：\(\boxed{1000}\) meters is the total distance traveled by the dog.
