Question

On a town map, each unit of the coordinate plane represents 1 mile. Three branches of a

bank are located at A(-3, 1) B(2, 3), and C (4, -1) . A bank employee drives from
Branch A to Branch B and then drives halfway to Branch C before getting stuck in
traffic.
What is the minimum total distance the employee may have driven before getting stuck
in traffic? Round to the nearest tenth of a mile.

Answer 1

`√(29) +√(5)` = 7.6 miles

Explanation:

`√((2+3^2)+(3-2)^2) +((√((4-2)^2+(-1-3)^2) )/(2) )`

`√(29) +(2√(5) )/(2)`

`√(29) + √(5)`

equals 7.6 (rounded to nearest tenth)
