Answer:
Ryan jogs faster than Hunter
Step-by-step explanation:
Huunter jogs four miles in 30 minutes
in 1 minute he jogs = 4/30= 0.1334 miles
ryan jogs 7 miles in 48 minutes
in 1 minute he jogs =7/48 = 0.145 miles
Ryan jogs faster than Hunter
T is time, and s is speed. T is inversely proportional to s
Answer:
50 feet
Step-by-step explanation:
Set up a 3-dimensional coordinate system (see the attached image).
This setup shows an axis that runs North-South (South is <u>negative</u>, North is positive), an axis that runs East-West (East is positive, West is negative), and an axis that runs Up-Down (Up is positive, Down is negative).
The two points in question are then:
First person's location (12, -20, -12), and the second person's location is (-20, 10, 12).
The distance between two points
and
is
![d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2+(z_2-z_1)^2](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B%28x_2-x_1%29%5E2%2B%28y_2-y_1%29%5E2%2B%28z_2-z_1%29%5E2)
![d=\sqrt{(-20-12)^2+(10-(-20))^2+(12-(-12))^2}\\\\d=\sqrt{(-32)^2+30^2+24^2}\\\\d=\sqrt{2500}\\\\d=50](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B%28-20-12%29%5E2%2B%2810-%28-20%29%29%5E2%2B%2812-%28-12%29%29%5E2%7D%5C%5C%5C%5Cd%3D%5Csqrt%7B%28-32%29%5E2%2B30%5E2%2B24%5E2%7D%5C%5C%5C%5Cd%3D%5Csqrt%7B2500%7D%5C%5C%5C%5Cd%3D50)
