Yeah okay, no settlements that far. Even if you managed to send out survival experts to somehow last that long, it's very likely that you would be taken as slaves, killed for their supplies, or eaten by cannibals, encounter bad weather, encounter foreign diseases, run out of supplies on the way.
Furthermore, in the amount of time given, it can be assumed that since 1 day = 1 year, your movement took approximately 34 days. Moving at the ideal 25 miles per day, that would be only 850 miles. The distance from Tanzania to Gibraltar is ≈3718 miles, using geographic approximations.
