Recalling the Seven-Step Strategy for Multi-Segment Route Analysis
Imagine you are a logistics operations trainer at a regional transport firm. You are designing a quick-reference guide for newly hired dispatchers. The guide must instruct dispatchers on how to solve multi-segment route analysis problems—specifically, how to determine the unknown segment speeds when only the individual times, a relative speed multiplier (e.g., speed of segment B is a multiple of segment A), and the total combined distance are known.
In essay format, recall and describe the standard seven steps of the distance, rate, and time problem-solving strategy (based on ) that dispatchers must follow to set up, solve, and verify these route calculations. Explicitly describe what is done in each step, from the initial visualization to the final verification process.

A campus maintenance technician completes an inspection in two segments. First, they use a motorized scooter for 1.5 hours at a speed of mph. Then, they switch to a utility cart for 2.25 hours, traveling at a speed 1.6 times faster than the scooter. The total distance covered is 51 miles. Match each description of the trip to its corresponding mathematical expression or equation.
A logistics coordinator is training a new hire on how to calculate average speeds for multi-segment delivery routes where the total distance and segment times are known. Arrange the following steps of the problem-solving strategy in the correct order.
A logistics fleet manager is calculating the travel parameters for a delivery drone on a two-part route. During the first segment, the drone travels for 1.5 hours at a base speed of miles per hour. During the second segment, it travels for 2.25 hours at a speed 1.6 times the base speed. Which expression correctly represents the drone's rate (speed) during the second segment?
A field service technician travels to two different job sites in one morning. During the first segment of the trip, they travel for 1.5 hours at a base rate of miles per hour. During the second segment, they travel for 2.25 hours at a rate of {}1.6r. If the total distance covered is 51 miles, the relationship is modeled by the equation . In this equation, the term {}3.6r represents the ____ traveled during the second segment.
A fleet management system is being programmed to calculate unknown delivery speeds for a route with a total distance of 51 miles. To correctly model the trip, the system should be programmed to set the sum of the times spent in each segment equal to the total distance of 51 miles.
