1.9.6 practice: modeling: multistep linear equations
1 circle the two boats you picked for your trip, and explain why you selected them. (3 points: 1 point for each selection, 1 point for your explanation)
2 i chose these boats because:
3. take what you know about traveling to and from the island by boat and write it as a sentence. (2 points)
4. let x be the speed of the boat you are taking to the island. the other boat's speed can then be written relative to the variable x. write the speed of each boat using the variable x. (2 points: 1 point for each boat)
5. each ship travels the same distance. remember that the trip time multiplied by the speed equals the distance. set the distances equal to each other to get the equation for the speed of the ship you are taking to the island. (1 point)
6. solve the equation from question 5 for x. what does this tell you? (3 points: 1 point for showing your work, 1 point for solving for x, 1 point for explaining the answer)
7. how fast does the second boat travel? show your work. (2 points: 1 point for showing your work, 1 point for the answer)
8. if the yacht trip costs $75, the tall ship trip costs $25, and the steamboat trip costs $40, how much does each trip cost per hour? (1 point)
