URGENT!! 3 x 2 matrix, please help as soon as you can!

Matrix A has two columns. When we describe a matrix by its dimensions, we report its number of rows first, then the number of columns. Matrix A is therefore a '3 by 2' matrix, which is written as '3x2. ... A 2x3 matrix is shaped much differently, like matrix B. Matrix B has 2 rows and 3 columns.

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."

the answer is 0.000652422

but if you ment to ask what is 6131 divided by 4, it is 1532.75.
