Answer:
Average speed of the two boats are 28 km/hr. and 24 km/hr.
Step-by-step explanation:
Let the average speed of the boat with larger speed is x km/h and that of the other boat is y km/h.
Now, given that x - y = 4 ...... (1)
If the distance, that the first boat covers in 3 hrs. is d km then the second boat covers d km in 3.5 hrs.
Therefore, and
Now, from equation (1), we can get
⇒
⇒ km/hr.
Again, km/hr.
Therefore, the average speed of the two boats is 28 km/hr. and 24 km/hr. (Answer)
Answer:
<h2>f(4) = -11, g(x) = 2 → x = 0</h2>
Step-by-step explanation:
Look at the picture.
So, let's make these two values improper fractions so they're easier to work with.
So, to get the rate he grew in those months we have:
And to get the rate he grew in one month we have to divide both our numerator and our denominator by 21 to get:
aka he grew 1.24 inches in a month.
The two numbers are 4.95 and 2.25.
<h3>
Explanation: </h3>
Let the two numbers be x and y. Given conditions,
...............................(1)
................................(2)
Adding equations (1) and (2), we get
Therefore
x=4.95 .......................(3)
Substituting value of x from (3) in (1), we get
y=2.25 ........................(4)
From (3) and (4), the two numbers are 4.95 and 2.25.
