Ezra's mother told her she was "moving at a snail's pace." how could ezra determine the average speed of a snail? a she can subtract the snail's density from the time it takes for it to cover a set distance. b she could divide a set distance by the time it takes the snail to move that distance. c she could add together the times it takes the snail to cover several set distances. d she could multiply the snail's mass by the time it takes it to cover a set distance.

if im undersanding the question correctly, its organized from 10

step-by-step explanation:

i need a picure

step-by-step explanation:

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."

14.3

step-by-step explanation:

add all the numbers together.

9 + 12 + 15 + 16 + 17 + 17 = 86

now, divide 86 by how many numbers we have: 6.

86 / 6 = 14.3
