Dave's regular driving speed = 40 mph
Dave's driving speed TODAY = 80 mph

Let d = the distance from Dave's home to work

Dave arrived at work 16 minutes earlier than he regularly arrives.
We can write: regular travel time in hours - 16/60 hours = today's travel time in hours

time = distance/rate, which means we can write: d/40 - 16/60 hours = d/80
Rewrite each fraction with denominator 240 to get: 6d/240 - 64/240 hours = 3d/240
Multiply both sides of the equation by 240 to get: 6d - 64 = 3d
Subtract 6d from both sides: -64 = -3d
Divide both sides by -3 to get: 64/3 = d

Answer: D
