Answer:
False
Step-by-step explanation:
Answer:
The charges will be the same after 4 hours.
Step-by-step explanation:
Total Amount = y
Number of hours = x for x > 2
Garage A: y = $7.00 + (x - 2)*3
Garage B: y = 3.25*x
Part 3: What is the cost to be equal?
3.25x = 7 + 3(x - 2) Remove the brackets
3.25x = 7 + 3x - 6 Collect terms on the right
3.25x = 3x + 1 Subtract 3x from both sides.
3.25x - 3x = 3x - 3x + 1 Combine
0.25x = 1 Divide by 0.25
0.25 x/0.25 = 1 / 0.25
x = 4 hours.
Remember that Distance = (Average speed)(Time)
Let x be the distance between Detroit and Columbus.
We know the journey from Detroit to Columbus took a time t, and the returning trip took a time t+

. We also know the Average speed of both journeys, so now we can set our equations:

Now, we can replace equation 1 into equation 2 to find t:




Now that we know t, we can replace it into our equation 1 to get the distance:


We can conclude that the distance between Detroit and Columbus is 220 miles. <span />
