Yair scooped a layer of sawdust into a composting toilet. The sawdust went through the seat and landed at the bottom of the pit 1.5 meters below the ground. The toilet seat is 0.4 meters above the ground. What is the distance between the toilet seat and the bottom of the pit? What was the change in height of the sawdust from the toilet seat to the bottom of the pit?

The distance between the toilet seat and the bottom of the pit is the sum of the heights of the seat above the ground and the pit below the ground.

Distance = height of seat + depth of pit
Distance = 0.4 meters + 1.5 meters = 1.9 meters

The change in height of the sawdust from the toilet seat to the bottom of the pit is simply the depth of the pit.

Change in height = depth of pit = 1.5 meters

To find the distance between the toilet seat and the bottom of the pit, we need to subtract the height of the toilet seat from the depth of the pit.

Distance between toilet seat and bottom of the pit:
= Depth of the pit - Height of the toilet seat
= 1.5 meters - 0.4 meters
= 1.1 meters

Therefore, the distance between the toilet seat and the bottom of the pit is 1.1 meters.

To find the change in height of the sawdust from the toilet seat to the bottom of the pit, we can simply use the depth of the pit.

Change in height of sawdust:
= Depth of the pit
= 1.5 meters

Therefore, the change in height of the sawdust from the toilet seat to the bottom of the pit is 1.5 meters.
