Answer:

I see what's happening here

You're face to face with greatness

And it's strange

You don't even know how you feel

It's adorable

It's nice to see that humans never change

Open your eyes, let's begin

Yes it's really me, breathe it in

I know it's a lot, the hair, the bod

When you're staring at a demigod

So what can I say except

You're welcome

For the tide, the sun, the sky

Hey, it's okay, it's okay

You're welcome

I'm just an ordinary demiguy

What can I say except

You're welcome

For the tide, the sun, the sky

Hey, it's okay, it's okay

You're welcome

I'm just an ordinary demiguy

Honestly, I can go on and on

I could explain every natural phenomenon

The tide, the grass, the ground

Oh, that was me I was messing around

I killed a snake, I buried its guts

Sprouted a tree, now you've got coconuts

What's the lesson?

What is the takeaway?

Don't mess with Maui when he's on a breakaway

And the tapestry here in my skin

Is a map of the victories I win

Look where I've been, I make everything happen

Look at that mean mini Maui just tikkity tappin'

Singing and scratchin'

Flipping and snappin'

People are clappin', hearing me rappin'

And bring the chorus back in

Well anyway, let me say you're welcome

For the wonderful world you know

Hey, it's okay, it's okay

You're welcome

Well, come to think of it, I gotta go

Hey, it's your day to say

You're welcome

'Cause I'm gonna need that boat

I'm sailing away, away

You're welcome

'Cause Maui's the ultimate guy

You're welcome!

Sandra normally takes 2 hours to drive from her house to her grandparents' house driving her usual speed. However, on one partic

Rudiy27

Answer:

Her usual driving speed is 38 miles per hour.

Step-by-step explanation:

We know that:

$s = \frac{d}{t}$

In which s is the speed, in miles per hour, d is the distance, in miles, and t is the time, in hours.

We have that:

At speed s, she takes two hours to drive. So

$s = \frac{d}{2}$

$d = 2s$

However, on one particular trip, after 40% of the drive, she had to reduce her speed by 30 miles per hour, driving at this slower speed for the rest of the trip. This particular trip took her 228 minutes.

228 minutes is 3.8 hours. So

$0.4s + 0.6(s - 30) = \frac{d}{3.8}$
