Answer:
The kinds of symmetry the letter H has Point , Line and plane symmetry
Explanation:
Point symmetry states that when every part has a matching part:
the same distance from the central point, but in the opposite direction.
Line of symmetry states that it creates two congruent figures that are mirror images of each other
Plane symmetry states a crystal that divides the crystal into two parts that are mirror images of each other.
Given letter H has line of symmetry because the letter folded in half in any way with the parts matching up.
Also, H has plane and Point Symmetry.
<u>Answer:</u>
x = 7.5 km/h
<u>Step-by-step explanation:</u>
• First calculate the distance covered by walking at 3 km/h for 45 minutes ( 0.75 h):
distance = speed × time
= 3 × 0.75
= 2.25 km
• Therefore, she covered 2.25 km of the total journey by walking. Since she was 6 km from the starting point at the end of the entire journey, we can calculate the distance remaining, which she had to run:
distance she had to run = 6 - 2.25
= 3.75 km
• Now we can calculate the speed of the 30 minute (0.5 h) run:
speed = distance ÷ time
= 3.75 ÷ 0.5
= 7.5 km/h
This means that she ran at 7.5 km/h for half an hour.
∴ x = 7.5
