Lesson 18:
RATE AND DISTANCE OF TRAVEL
Students will calculate the distance and the rate of the speed of the U.S. Brig Niagara, traveling with the current and returning against the current. They will use mathematical skills to calculate distance and rate of speed and apply these skills to the ship, apply knowledge of velocity and direction of the wind to speed of the current, use linear systems to calculate distance traveled. Learning to compute rate and distance of travel is a necessary skill aboard a ship. Teachers will review mathematical skills necessary to compute rate and distance of travel and give students the opportunity to practice these skills.
ACTIVITIES: 1. Calculate the rate of speed of the U.S. Brig Niagara to and from a given point and calculate the distance traveled. 2. Apply this knowledge to practical information to determine why it is necessary. 3. Discuss the reason this information is vital on board ship. 4. Evaluate the format of the equations and the calculations. (Mathematics Standards) SHIP’S STORES/REFERENCES -- Mathematics teachers
