Recall your d = rt, distance = rate * time.
notice, the distance are the same, say it was "d" miles.
and if car A is travelling at a speed of say "r" mph, then B is going at "r+15" mph.
how far is B going? well, r + 15.
Answer:
22.74 liters
Step-by-step explanation:
GIven data
Felix's washing machine uses 6 gallons of water
we are told that A gallon is approximately 3.79 liters
Hence if a gallon is approximately 3.79 liters
then 6 gallons of water will be x liters
cross multiply we have
x= 6*3.79
x= 22.74 liters
Hence 6 gallon will be 22.74 liters
The number of gallons of water in the tank at t=10 is
... W(10) = 160,000 -10(8000 -10) = 80100
The number of gallons of water in the tank at t=10.5 is
... W(10.5) = 160,000 -10.5(8000 -10.5) = 76110.25
The rate of change over the interval is
... (W(10.5) - W(10))/(10.5 - 10) = (76110.25 - 80100)/(0.5) = -7979.5
The average rate of change in the number of gallons of water in the tank over the interval is -7979.5 gal/min.
The sign is negative, so the amount of water is decreasing.
