A regular tank is being designed with an internal catwalk around the inside as shown. For functional reasons, the walk way cannot be more than 3 in. above the liquid. The liquid level in the tank will be maintained 3/4 full at all times. What height dimension for the walkway should be put on the drawing? Please answer step-by-step, Thanks Someone please answer this, I wasted all my points for this problem to be on here, Thanks I appreciate it..

I tried to put the drawing on here but it wouldn't let me. ​

- "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."

it would take 7/10 of an hour too fill the pool.
