To solve this problem you must apply the proccedure shown below:
1. You have that Darren can get to work in
`30 minutes` and with the traffic and lights, he can average
`30 mph`.Therefore, you must apply the formula for calculate the distance, which is:

`d=Vt`
Where
`V` is the speed and
`t` is the time.
2. The time in hours is:

`30 min=1/2 h`
3. Substituying values, you have:

`d=(30 mph)(1/2 h) \\ d=15 miles`
The answer is:
`15 miles`
