Distance Calculation: Converting 1000m Walking + 1km Running

Let's solve the problem step-by-step:

Darrel walks a distance of $1000$ meters every day as part of his exercise.

Darrel also runs a distance of $1$ kilometer daily. To find this distance in meters, we use the conversion factor:
$1\, \text{kilometer} = 1000\, \text{meters}$

Thus, Darrel runs $1000$ meters.

To find the total distance Darrel covers each day, add the distance he walks to the distance he runs:

Total distance = Walking distance + Running distance

Total distance = $1000 + 1000$

Total distance = $2000$ meters

Therefore, Darrel covers a total of $2000$ meters each day.
