Answer:
Total distance= 15.055 unit
Step-by-step explanation:
Distance between the first journey i.e from her office to the supermarket is calculated as follows given the coordinates.
(-5,-7) and (4,-6)
The distance between those tow points
Is
= √((4-(-5))² +( (-6)-(-7))²)
= √(9²+1²)
= √ 81+1
= √ 82
= 9.055
Noe the distance between the second journey traveled i.e from the supermarket to her house is calculated as follows given the coordinates.
(4,-6) and (-2,-6)
Distance= √((4--2)² +( -6--6)12
Distance = √(4+2)² + 0
Distance = √ 6²
Distance = 6
Total distance= 9.055 + 6
Total distance= 15.055
