b. 55 units
Step-by-step explanation
due to the displacements are vertical or horizontal we can add the length of each segmento to find the total,so
so
a)let
as this is a vertical line, we nned to subtract the y-coomponet of the points
so , PQ= 16
Step 2
b) Distance from Q to R (green)
QR
Let
as this is a horizontal line, we need to subtract the x-coomponet of the points ,so
so
QR=24
Step 3
finally, segment RS (blue)
let
as this is a vertical line, we nned to subtract the y-coomponet of the points
Step 4
finally , add the segments to find the total distance from P to S
therefore, the answer i
b. 55 units
I hope this helps you
