As a logistics coordinator for a delivery service, you are modeling a route that includes both flat city streets and uphill sections. Match each component of the distance-rate-time strategy with its correct mathematical representation or definition.

A fleet manager is analyzing a courier's performance data. The courier's speed biking uphill is 0.6 times their speed on flat streets. If the flat speed is represented by the variable $r$, which expression correctly represents the uphill speed for use in a distance-rate-time model?

A logistics supervisor is training a new coordinator to calculate delivery speeds across different terrains. To solve for the unknown flat and uphill speeds when the total distance and the relationship between the speeds are known, arrange the following steps of the distance-rate-time strategy in the correct logical order.

An operations analyst is modeling a delivery route that consists of a flat segment followed by an uphill segment. To find unknown speeds when the total distance of the route is known, the analyst uses the distance-rate-time strategy to set the sum of the distances for the individual segments equal to the ____ distance of the trip.

In a distance-rate-time model for a courier's route consisting of a flat segment and an uphill segment, if the total distance of the entire trip is known, the equation to solve for the unknown speeds is formed by setting the sum of the distances of the individual segments equal to the total distance.
