Answer:
Step-by-step explanation:
Let's put in some numbers to make this easier to understand.
Let's say she has to travel 20 km.
On Monday, she travels at 4 kph. This takes 5 hours.
On Tuesday she travels 25% faster, at 5 kph. This takes 4 hours.
To figure percent reduction we take
100 % * (old - new) / old
100 % * (5 hr - 4 hr ) / 5 hr
100 % * 1 hr / 5 hr
100 % * 0.20
20% reduction.
Applying the Pythagorean theorem, the height of the building is: 24.9 m.
<h3>How to Apply the Pythagorean Theorem?</h3>
Where c is the length of the hypothenuse of a right triangle, and a and b are the legs of the right triangle, the Pythagorean theorem states that:
c = √(a² + b²).
The diagram of the building and its shadow form a right triangle as shown in the image below, where:
a = height of the building
b = 26
c = 36
Applying the Pythagorean theorem, we will have:
a = √(36² - 26²)
a = √(36² - 26²)
a = 24.9 m
