Answer:
5 km
0
Explanation:
The question says the truck travelled to and fro from the stone quarry.
When going to the stone quarry, the distance was 2.5 km to the east.
On returning, the distance back is also 2.5km
Therefore total distance travelled is 2.5km + 2.5km
= 5km
The displacement 8s dependent on what is the initial and also the final position. The initial and the final position are one and the same thing. Because the truck starts and goes back to the same position, the displacement is zero.
Answer:
I'm not sure if you maybe forgot to add in some information but I can give you the equation you will need to solve this..! (just without the bit of infomration you might need)
In this case you'll be solving for t and I can help you with your first step, you'll divide 2 by 4, getting you to:

The weight of the water displaced is the same as the total weight of the
wood block. The fact that 1/3 of the block is above the water level
does not matter if you just weigh the total block of wood , then the
weight of the total block of wood = the weight of the water displaced by
the block of wood. If you want to find density of the block of wood
that is a different question - then you need the volume of the block of
wood and the information about one- third of the total weight . I hope this helped</span>
They travel at different speeds
