Answer: -23
Step-by-step explanation:
The change in y value can be determined by subtracting the first value from the second.
-19 - 4 = -23
Or if you think about it logically you are going from a positive number to a negative so the total distance will be greater than both of your values.
Answer:
192.972 mi/h
Step-by-step explanation:
To solve this, you have to add up all of the speeds and divide by how many values there are.
So if all of them are added together, it equals 771.888. Then, you divide this number by 4 to find the average. In this case, the average is 192.972mi/h.
This kind of problems requires to add the working velocities. The total velocity is the sum of the individual velocities.
Anita's velocity = 1 pool/8 hours
Chao's velocity = 1 pool/6 hours
Combined velocity 1/8 + 1/6 = (3 + 4)/24 = 7/24 pool/hour
Time = 1 pool / (7/24) pool/hour = 24/7 hour =3.43 hours
