Question

using the paths shown, how long is the shortest route from seaside to belleville? seaside 7.4 mi centerville 5.2 mi somerville 11.8 mi 11.9 mi belleville

Explanation:

Step1: Identify possible routes

There are two possible routes from Seaside to Belleville. One via Centerville and Somerville with length $7.4 + 5.2+11.9$, and the other directly from Seaside to Somerville and then to Belleville with length $11.8 + 11.9$.

Step2: Calculate first - route length

$7.4+5.2 + 11.9=24.5$ mi

Step3: Calculate second - route length

$11.8+11.9 = 23.7$ mi

Step4: Compare lengths

Since $23.7<24.5$, the shorter route length is $23.7$ mi.

Answer:

$23.7$
