It takes you 54 seconds to walk from the first ground floor of a building to the third floor. How long will it take to you to walk from the first floor to the sixth floor

112 seconds

Step-by-step explanation:

because add 54 twice

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.

b, i believe, but not sure.
