probably not long.
My Answer:This is one of those questions that will depend on where you are observing from.If you are the one in a black hole and the most basic measure of time and death are used: Once you are in the Black hole your death would be instant.
Traveling into the hole and dieing may take virtually forever because of the way a Black Hole distorts time and gravity.
If you could figure out how to watch from out side no human could live long enough to see a person die and confirm that he/she was dead. Again this is due to distortion of time.
4 days on Pluto would be 25.6 Earth days.
well it would take approximately 49 earth days
A day on Venus is equal to 243 Earth Days. So a week on Venus would be 1,701 Earth days or 4.65 Earth years. However, a Venus year is only 224 Earth Days!!! so a week could be 4.3 Earth days
One Venus day equals 243 Earth days. Seven Venus days equals 1701 Earth days, or 4.66 Earth years. 243 days is the Sidereal day length,but remember Venus has a Solar day of only 117 Earth days.
It would take over 16,000 Earth days, or around 44 Earth years, for a spacecraft to travel from Earth to Neptune at its average distance from Earth. The actual time would depend on the speed and trajectory of the spacecraft.

90 days
10.7hours of earth
In Earth days t would take a huge number because in Earth years it is 164.79!
The days would be longer, and the gravity would be higher if the rotation time of earth was longer. The days would be shorter, and there would be less gravity on Earth if the rotation time decreased.

It takes Mercury 58.65 earth days day to rotate so that would probly be the closest to 59-60 earth days
Mainly, to revolve around the Earth in 15 days, the Moon would have to be closer (you can calculate the ratio using Kepler's Third Law). This would make the tides stronger.
the earth would be darker than what it is these days.
