# Dakota lives 1,500 meters from school. She leaves for school, walking at a speed of 60 meters per minute. How do you write an equation for her distance d in meters from school after she walks for t minutes?

$R = 1500 - \left(60 \cdot t\right)$

#### Explanation:

Total $d$istance walked = $1500$ meters.

Dakota's $r$ate is $60$ meters per minute.

The equation for $d$istance walked over time = $r \cdot t$.

Therefore the distance walked over $t$ime = $60 \cdot t$

The equation for distance remaining (let's call it $R$ is 1500 - (60 * t).

so the remaining distance to walk after a time $t$ can be written as"
$R = 1500 - \left(60 \cdot t\right)$
