Paula walked ¾ mile in 10 minutes. Hannah walked ⅘ mile in 15 minutes. What was the difference in their speeds, in miles per hour?

1 3/10 (SORRY IF ThIS IS WRONG)

Step-by-step explanation:

3/4 mile x 6 = 4 1/2

(we multiply by 6 because to get 60 minutes/1 hour you need to multiply 10 minutes by 6)

60/15=4

(we will multiply by 4 because we need that to get 1 hour)

4/5 x 4 = 3 1/5

4 1/2 - 3 1/5 = 4 5/10 - 3 2/10 (we do that so we can subtract easier)

4 5/10 - 3 2/10 = 1 3/10

point a is the center of this circle.

the ratio of the lengths of (ef/bc) and (ad/ih) is 2: 1.

step-by-step explanation:

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.
