Answer:
Step-by-step explanation:
distance between two points:
we have:
To solve this problem we will start by calculating time needed for each of them to fill the pool.
We have formula:
Volume = rate * time
Or
time = volume / rate
Wilma:
time = 9900 / 900
time = 11h
Betty:
time = 9900 / 500
time = 19.8h
Now we substract these two numbers:
time_difference = 19.8 - 11 = 8.8h
Betty needs 8.8 hours more than Wilma to fill the pool.
4 2/5 = 22/5
3 1/7 = 22/7
22/5 x 7/22 = 154/110 = 7/5
The answer is 1 2/5

Answer: m+n-mn</h3>
You can write mn as m*n
=================================
Explanation:
The sum is the result of adding two or more numbers. Saying the sum of m and n means m+n.
Then we subtract off the product of m and n. The product is the result of multiplying m and n. We say m*n or mn to indicate their product.
Overall, we end up with m+n-mn
