Answer:

D. 24 lb

Explanation:

Total weight lost

3-1+22 = 24 lb

Tina has lost 24 pounds in total during the 13 weeks

salantis [7]

Answer:

They will never meet.

Explanation:

Given that three sharks are located at the vertices of an equilateral triangle whose side equals LL. They all start moving simultaneously with a constant speed vv, with the first shark heading constantly toward the second, the second toward the third, and the third toward the first. How soon will the sharks converge at one point ?

Since the three sharks are located at the vertices of an equilateral triangle whose side equals, and the first shark is moving toward the second, the second is moving toward the third, and the third shark is moving toward the first, the movement of the three shark will form a circular motion.

Since the three sharks are moving at a constant speed, the three sharks will never meet because the distances between them are also the same.

The three sharks will therefore continue to move till infinity.
