1. Anthony walks to the pizza place for lunch. He walks 1km east then 1km south east again.

TiliK225 [7]

The answer is: distance is 3 km, displacement is 2.24 km.

Distance is total length: 1 km east + 1 km south + 1 km east again = 3 km
Displacement is the hypotenuse of the right triangles which sides are 1 km east and 2 km south. According to the Pythagorean theorem:
a² + b² = c²
1² + 2² = c²
1 + 4 = c²
5 = c²
c = √5
c = 2.24 km

Aliyah marks a line on her driveway with a piece of chalk and another line 50ft away Then she stands with both feet at the line

Mariulka [41]

Answer:

Speed

Explanation:

Aliyah must have been trying to find her speed.

The speed is a measure of how fast an object or a body is and it is calculated by finding the ratio of distance with time. Mathematically,

speed = $\frac{distance}{time}$ with a unit of m/s.

<em>Hence, with the distance measured on the ground and Aliyah trying to find the time it will take her to cover the distance while running, she must have been trying to find how fast she can run, that is, speed. </em>
