Answer:
52 meters
Explanation:
The man runs a distance D meters at 4 m/s. The bear runs a distance D+26 meters at 6 m/s.
The time it takes the man to reach the vehicle is:
t = D / 4
The time it takes the bear to reach the vehicle is:
t = (D + 26) / 6
If they reach the vehicle at the same time:
D / 4 = (D + 26) / 6
6D = 4(D + 26)
6D = 4D + 104
2D = 104
D = 52
The man can return safely to his vehicle if D is less than 52 meters.
