Distance = Speed x time = 162 x 3 = 486 miles/hour

Answer: 486 miles/hour

Reduce:

162 miles

--------------- = 54 mph

3 hrs

If we start with distance = rate times time, we can solve for rate:

rate = distance / time. That's what I've just done (above).

Raul’s grandfather is Miguel, and Raul’s sister is Paula. Raul’s age is the same as his grandfather’s age minus 60 times the age

Lostsunrise [7]

Answer: The answer is x = 65 - 60y.

Step-by-step explanation: Given that Miguel is the grandfather of Raul and Paula is Raul's sister.

Now, let 'x' years be the age of Raul and 'y' years be the age of Raul's sister (Paula).

Also, given is the following information -

Raul's age = Grandfather's age - 60 × sister's age.

Since the age of Miguel, Raul's grandfather is 65 years, so we can write the following equation to find Paula's age

$x=65-60\times y\\\\\Rightarrow 60y=65-x\\\\\Rightarrow y=\dfrac{65-x}{60}.$

Thus, we can find Paula's age (y) using the equation

$y=\dfrac{65-x}{60},$

where 'x' is the age of Raul.

Part 1:

Step 1:

Find the value of G(16)

Using the equation for g(x) =√x, replace x with 16 and solve:

g(16) = √16 = 4

Step 2:

Now using the answer for g(16) replace x in the equation fir f(x) with 4 and solve:

f(x) = x +2

f(4) = 4+2 = 6

Part 2:

following the same steps as part 1:

f(g(x)) would be replacing x in the equation ofr f(x)with the equation for g(x)

f(g(x)) = √x +2
