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!
Given: 3^(x − 4) = 6
To find: Solution to the given expression using change of base formula
Answer: The given expression is 3^(x − 4) = 6 Taking log on both sides, we get - log(3^(x − 4)) = log6
(x - 4) log3 = log6
x - 4 = log6/ log3
x - 4 = (∵ change of base formula)
x - 4 = 1.631
x = 5.631
Thus x = 5.631 is the answer in the nearest thousandth.
Answer:
n=4p
Step-by-step explanation:
18n-7p-15n=5p
3n-7p=5p
3n=5p+7p
3n=12p
n=12p/3
n=4p
