Hands-On Equations Distance Problem - Honors

Errata Sheet

Hands-On Equations Verbal Problems Book

Level III Distance Problem, Page 107/44 and Solution Page 133/44

This problem has been modified as shown below.

This may be considered an honors problem

for students in grades 6 - 9.

The solution remains the same as that shown in the book.

44. A motorboat, after traveling for one hour in tranquil waters, begins to go downstream with the current, thereby increasing its speed by 2 miles less than one-third of its original speed. After going downstream for one hour to reach its destination, and after unloading one of the passengers, it reversed direction and went upstream against the same current for one hour to arrive at a refueling station. At that point the motorboat still needed to travel an additional 36 miles to reach its starting point. Find the speed of the motorboat in tranquil waters, and the distance it traveled to arrive at its destination. [III, 25]
