Water is leaking out of a container. At 2:30 p. m., there are 42 pints of water in the container. At 4 p. m., there are 30 pints of water in the container. If the water continues leaking out of the container at the same rate, how much water will be in the container at 6:30 p. m.?

A. 26 pints

B. 50 pints

C. 25 pints

D. 10 pints

The answer is D. it goes down 12 every 1 and a half hours so 4/1.5 =2.6666

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.
