Velocity and perimeter

Please show all steps in solving these problems. Thank you

1. The rectangular swimming pool measures 20 feet by 70 feet and contains a path of uniform width around the four edges. The perimeter of the rectangle formed by the pool and the surrounding path is 204 feet. Determine the width of the path.

2. Use the formula :Time traveled = DISTANCE TRAVELED
Average Velocity

A passenger train can travel 240 miles in the same amount of time it takes a freight train to travel 160 miles . If the average velocity of the freight train is 15 miles per hour slower than the average velocity of the passenger train , find the average velocity of each.

Solution Summary

This shows how to use perimeter to determine the width of a path, and how to find velocity given relative velocity.
