<u>Step-by-step explanation:</u>
Let x represent the number of minutes to the US and
let y represent the number of minutes to Brazil
and make sure their sum is not greater than $20
.03x + .06y ≤ 20
Answer:
A. 3 and a half hours (3 hours 30 minutes)
B. 72 dollars
Step-by-step explanation:
A. first do 512-92 = 420
420/120 = 3.5 hours
B. 2 hours = 240 dollars
312 - 240 = 72 dollars for the parts

Before we do anything, we need to find out how fast we are going in the first place.
We know we are going 1.5 miles per minute and that there are 60 minutes in an hour, so we can find our speed in mph. All we have to do is multiply 60 and 1.5.
That gives us 90 mph.
Next, the problem says that we reduce our speed by 15 mph, so you would subtract 15 from 90.
That gives us 75 mph.
The last thing the problem says is that we reduce our speed by one third, so first we need to know what one third of 75 is. We can find that by dividing 75 by 3.
That gives us 25
But we aren't finished yet! We still need to subtract 25 from 75 to get our current speed. When we do this we get our final answer of...
50 mph
