Answer:
5 km
Step-by-step explanation:
We are given the distances walked by Maria;
We are required to determine the displacement from her starting point;
- We are going to use Pythagoras's theorem;
a² + b² = c²
Taking, the distances towards south and towards west as the legs of the triangle;
Then, c² = 3² + 4²
= 25
c = √25
= 5 km
Therefore, the displacement from the starting point is 5 km
Part A would be $75+.$55m and part B would be $165 +$75=$240
Paul's rate before the pay rise = 7.0
The increase = 4/100 * 7.0 = 0.28
Paul's rate after the pay rise = 7.0 + .28 = 7.28
