First, add the 2x and x together for 3x
Then add 3 to both sides of the equation
Finally, divide each side by 3.
<u>Picture 2:</u>

First, add 7x and x together for 8x
Then, minus 20 from both sides of the equation
Finally, divide each side by 8.

Hello!
The time difference between checkpoint 1 and checkpoint 2 is an hour and a half.
At checkpoint A, the total amount of miles driven is 120. At checkpoint B, the total amount of miles driven is 195.
To find the amount of miles driven between checkpoint 1 and 2, you will subtract the amount of miles at checkpoint 1 from checkpoint 2:
195-120= 75
The car drove 75 miles between 1:00pm to 2:30 pm. Because the total time between the checkpoints was an hour and a half, we can divide it by three (90 minutes total). We also need to divide the number of miles (75) by three to find an accurate answer.
90/3=30
75/3=25
The car drove 25 minutes in half an hour. Now, one hour consists of 60 minutes, so we will multiply both calculations by 2 (for the total hour and the total amount of miles driven in the hour):
30x2=60
25x2=50
The car drove 50 miles per hour between checkpoints A and B.
I hope this helps you! Have a great day!
