What can be used on this is the distance over time formula, so what you,do is divide 228 by 4 to get the distance traveled in one hour. And 288/4=57. So they traveled 57 mi in one hour. Hope this helped.

Okay, so all you would have to do is find the unit rate, and to do that, you would divide 4 INTO 228, (228 divided by 4), which would be 57, so they drive 57 miles PER HOUR.
I hope I helped! =D

If it takes 5 gallons of gas to drive 115 miles, how many miles can be driven using 7 gallons of gas?
elena-s [515]

Answer: The answer is 161

Step-by-step explanation: First you write 5 and 115 as a proportion, 5/115, (for every 5 gallons you can go 115 miles). Then you find out how much you can go with 1 gallon, divide by 5. Then multiply that by 7, since that is how many gallons you need to find out.

Hope this is helpful!

Mrs Franklin's speedometer said she was driving at a rate of 48 miles per hour. When checking the accuracy of her speedometer, a
Ket [755]

The percent error is 4.167 %

<em><u>Solution:</u></em>

Given that, Mrs Franklin's speedometer said she was driving at a rate of 48 miles per hour

When checking the accuracy of her speedometer, an Automotive Specialist recorded her speed at 50 miles per hour

<em><u>The percent error is given by formula:</u></em>

Percent error is the difference between a measured and known value, divided by the known value, multiplied by 100%

\text{Percent error } = \frac{\text{experimental-theoretical}}{theoretical} \times 100

From given,

Experimental value = 50

Theoretical value = 48

<em><u>Substituting the values in formula, we get,</u></em>

Percent\ Error = \frac{50-48}{48} \times 100\\\\Percent\ Error = \frac{2}{48} \times 100\\\\Percent\ Error = 4.167

Thus the percent error is 4.167 %

Whoever responds first will get marked best!!!!!The Garcia family is driving from 3,272 miles from San Diego, CA ot Bar Harbor,
mojhsa [17]

Answer:

8

Step-by-step explanation:

We know that in 5 days they have travelled 2045 miles. This means that their per day average for travel is 2045/5=409 miles per day.

Now the distance left is 3272-2045=1227 miles.

And if we divide the average miles with the miles left, it gives us= 1227/409

=3

So, the total time taken for travel will be= 5+3=8 days

I guess this is the way to do it.
