Please help me it’s sixth grade math

These are absolute value questions. When you are finding the absolute value of a number, like -3.4 for example, the number is always positive. So if you wanted to find the absolute value of -3.4, the answer would be 3.4.

The answers are:

1. 5

2. 12.9

- "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."

could u provide us some answer choices or hmm idk maybe a table for us to anser with ? ?
