Step-by-step explanation:
The number of people to paint the bridge is inversely proportional to the number of hours it takes.
(If there are more people, it will take less time etc.)
9 people can paint the bridge in 5 hours.
=> 2 people can paint the bridge in 5 * (9/2) = 22.5 hours.
Answer:
2.6 m
Step-by-step explanation:
In the attached diagram
Consider Triangle ABC
Our goal is to determine the distance of Jen (at point A) to Holly (at Point D).
In Triangle ABC
In Triangle BDC
Applying Pythagoras Theorem
Now, |AC|=|AD|+|DC|
6.3103=|AD|+3.7136
|AD|=6.3103-3.7136
|AD|=2.5967
|AD|=2.6m (correct to the nearest tenth of a metre)
The distance of Jen from Holly is 2.6m.
