Answer:
n = ( 40 - m )
Step-by-step explanation:
On a particular day, Ricardo drank a total of 40 fluid ounces of water.
If he drank m fluid ounces of water in the morning of that day, then the number of fluid ounces of water he drank the rest of the day is given by (40 - m) fluid ounces.
If n represents the number of fluid ounces water that he drank the rest of the day, then we can write the equation as
n = ( 40 - m )
Therefore, the above equation can be used to find n. (Answer)
Answer:
For this question, all we need to do is to apply the formular to calculate the distance since we already had the time which is h hours and the speed which is 400 miles per hour:
d = v × t = 400 × h
So the correct answer is number 3.
