Para ligar Aldeia Nova a Aldeia Velha foi construído um túnel com
25 metros de comprimento e 6
metros de largura. Qual o volume de
terra que foi tirado para ser aberto
o túnel. Considera 3,14 como valor
aproximado de π.

17 1/3

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."

nope lol
