Answer:
1 hour 37 minutes
Step-by-step explanation:
From the image attached, we can see the start and end time represented by the clock. To calculate the length of time that Maria and her friends rode, we just have to subtract the start time from the end time.
From the end time clock, we can see that the end time is 2:24, while from the start time clock, we can see that the start time is 12:47. Hence, the length of time they rode is:
Length of time for bike ride = 2:24 - 12:47 = 1 hour 37 minutes

Step-by-step explanation:
The question is incomplete because the coordinates of A, B and C were not given in the question.
However, the following explanation will guide you...
The midpoints, C of two point A and B is calculated as:
Where are the coordinates of A
and
are the coordinates of B
Take for instance, the given coordinates are
A(4,6); B(2,4) and C(3,5)
Then;
Plug in these values in the given formula:
In that case,
C is really the midpoint
To the b part: <em>Explaining why ratio 1:1 is used</em>
The reason is that both parts of the ratio are in equal proportion (1 and 1);
Because of this equal proportion, ration 1:1 is right to calculate the midpoint
