What does 324.6 times 0.12 equal this is my last question so i will give you a 100 points if answer right

the answer is 38.952

answer:

38.952

step-by-step explanation:

324.6 times 0.10 equals 32.46

324.6 times 0.02 equals 6.492

add them together you get 38.952

- "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."
