The rate in m³/m² is 40m³/m².
1 m³ is literally a cube with sides that are 1 m in length. 1 m = 100 cm, so each side of this cube is 100cm in length. Finding the volume means multiplying length by width by height:
100(100)(100)=1,000,000 cm³ in 1m³.
We know that we have 25,000cm³ of mulch; we divide to find how many cubic meters this is:
1,000,000/25,000 = 40 m³.
This makes the rate 40m³/m².
For every 9 children, there are 4 adults.
If there are 39 children and adults, we can work backwards to find the answer.
Lets start by multiplying 9. Lets do 3. 9 x 3 = 27.
Ok, now we have an estimate of 27 Children, now all we have to do is multiply the number of adults by 3.
Now we can multiply 4 x 3. 4 x 3 = 12. Now we have the number of children and adults.
Now lets add these together. 12 + 27 = 39! Perfect! Now we know that there are 27 children, and 12 adults.
Hope this helps!!
To find her speed, divide the total distance by the total time:
12.5 miles / 5 hours = 2.5 miles per hour.
