The route calculation uses which inputs to estimate travel time and distance?

• A. Street addresses only
• B. Postal codes only
• C. City names only
• D. Latitude and longitude

Answer: (D)

Precise location coordinates are what route calculations rely on to estimate travel time and distance. Latitude and longitude pin down the exact point on the map for both the starting point and the destination, allowing the routing engine to trace the correct road network, measure the distance along the chosen path, and apply typical speeds for each road segment to compute time. Street addresses, postal codes, or city names are too coarse on their own because they can map to many possible points within a street, district, or area. This ambiguity would lead to unreliable distance and time estimates. In practice, an address is usually converted to coordinates (geocoded) first, but the fundamental need is the precise lat/long to ensure accurate routing.
