Commuting from Diamond Bar to Century City – is it doable?

I have a summer job in Century City coming up and plan to live in Diamond Bar with family for the 2 or so months that the job will go on for. My question is will it be possible to commute by car?

I need to be in an office 5 days a week. How long would mornings and evenings take most likely? Maps claim 1-1.5 hours in the morning and 1 hour at night…

Thanks!
