Running burns more calories than walking per unit time (30min run vs 30min walk).
Which burns more calories per unit distance (4 mile run in 30minutes vs 4 mile walk in 60minutes)?

the run will, which I find surprising because you would think the elastic energy return from running would make it cheaper energywise but it doesn't for some reason
Running burns slightly more calories per unit distance vs walking, but the difference is small. Practically, a mile is a mile no matter how fast you cover it.
The faster you ambulate, the less energy efficient you are. Atmospheric resistance, vertical displacement, and other mechanical factors all add up.

Because running involves having both feet off the ground (part of the time), each step involves a raising and lowering of the center of mass against gravity. This is more energy-costly than walking, in which it's possible to keep the CM at (well, closer to) one level.
Running and walking are nearly identical per unit distance. Running is slightly more (maybe 10%)due to the greater vertical component.
If you are really looking for more calories per unit distance, RACE WALKING will burn more than walking and running per mile. It is akin to driving a car down the freeway in 4th gear (of five) - not as fuel efficient. This is because you are at a speed where your body would normally tell you to run, but you are fighting that urge and continue to walk, thus lowering economy.
