80 kilometers is equal to 80,000 meters. This is greater than 1000 meters.
Answer:
Time taken = 6.2 hours
Step-by-step explanation:
Firstly, we will calculate the rate of each person per hour. Then we combine the rates and afterward divide the number of envelope they could address by the combined rate.
Casey can address 20 envelopes at the rate of 20 per hour.
Casey rate = 20 envelope per hr
Anne can address 44 envelope in 2 hours
Anne rate = 22 envelope per hr
Paula can address 68 envelope in 3 hours
Paula rate = 68/3 envelope per hr
Time it will take them to address 400 envelope can be solved below
Add their rate = 20 + 22 + 68/3 = 42 + 68/3 = (126 + 68)/3 = 194/3
Time = 400 ÷ 194/3 = 400 × 3/194 = 1200/194 = 6.1855670103
Time taken = 6.2 hours
To do this, we calculated all possible solutions to this problem:
what x what = 52
Note that "what" and "what" in the above problem could be the same number or different numbers.
Below is a list of all the different ways that what times what equals 52.
<span>1 times 52 equals 52
2 times 26 equals 52
4 times 13 equals 52
13 times 4 equals 52
26 times 2 equals 52
52 times 1 equals 52

Left is plus right is negative -11-(-15)=4 so you know 4 to the left
AB=EF
ABEF=ABF+AEF
