Answer:
30 mL/h
Step-by-step explanation:
You want the rate 336 ml in 11.2 h as a rate in simplest form.
<h3>Unit rate</h3>
The rate can be expressed in simplest form in a number of ways. We usually want rates involving time to be expressed with time units in the denominator:
(336 mL) / (11.2 h) = 30 mL/h

<em>Additional comment</em>
Medicine is often prescribed on a "per day" basis. In 24 hours, this rate would be ...
(30 mL/h)×(24 h/day) = 720 mL/day
The machine setup to dispense this medicine might use time units of minutes:
(30 mL/h) / (60 min/h) = (1/2) mL/min
Answer:
Present age of son = 15 years
& Present age of father = 40 years
Step-by-step explanation:
- Let the son's present age be x years
- -> Father's present age = (x + 25) years
- 10 years ago:
- Son's age = (x - 10) years
- Father's age = (x +25 -10) = (x +15) years
- It is given that: 10 years ago father was six times as old as his son
- -> Present age of son = 15 years
- & Present age of father = 40 years.
Substitute 1 in for x, -2 in for y, -3 in for z, and solve.
(1³)(-2)(-3²) + (1²)(-2²)(-3²) + (1)(-3)
-18 + 36 - 3
D) 15
