Scuba diver dove from the surface of the ocean to an elevation of -89 9/10 feet at a rate of -24 ft./min. after spending 11 minutes at that elevation the diver ascended to an elevation of -18 9/10 feet the total time for the dive so far was 18 1/8 minutes. what was the rate of change in the divers elevation during the ascent round your answer to the nearest hundredth

- "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."

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11-1 > 1-1+a

-12 > a

the answer is 1 becuz if it were 1.0 that would rip apart the entire so ya. : )
