Answer:
The family's average rate of travel for the day was 59.0 MPH.
Step-by-step explanation:
From 10:15AM to 4:45PM, they travelled a distance of 383.5 miles and a total of 6 hours and 30 minutes.
There are 60 minutes in an hour. 30 minutes translates into 1/2 an hour or .5
So, 6.5 hours and a total distance of 383.5 miles.
Velocity (MPH) = Distance (in miles) / Time (in hours)
MPH means Miles Per Hour
Variables:
Velocity (MPH) = x
Distance (in miles) = 383.5
Time (in hours) = 6.5
Plug in the variables into the formula
x = 383.5 / 6.5
Divide
x = 59.0 MPH
The radius is 10.. the radius is half of the diameter
<h3>x is 2 and y is -2</h3>
<em><u>Solution:</u></em>
Given that,
3x-2 equal x-y equals 4
Which means,
3x - 2 = x - y = 4
Therefore,
x - y = 4
Also,
3x - 2 = 4
Simplify above expression
3x - 2 = 4
3x = 4 + 2
3x = 6
Divide both sides by 3
x = 2
Substitute x = 2 in x - y = 4
2 - y = 4
y = 2 - 4
y = -2
Thus x is 2 and y is -2
