Answer:
Hello, In elementary geometry, the property of being perpendicular (perpendicularity) is the relationship between two lines which meet at a right angle (90 degrees). The property extends to other related geometric objects. A line is said to be perpendicular to another line if the two lines intersect at a right angle.
Hope this helped!!
Both traveled the same speed: 3cm/3s= 1m/s and 6cm/6s= 1m/s
2*4= 8 meters
You could multiply every centimeter by the scale of 4 because 1 cm= 4 meters.
I hope this helps!
