The inner core because IT is the center of earth
1800 to 1820 is 20 minutes.
1830 to 1838 is 8 minutes.
1840 to 1905 is 25 minutes.
The total time travelled is 20+8+25 = 53 minutes = 3180 seconds.
Since the question does not state the distance between Glasgow and Edinburgh, let the distance be X.
The average speed is X/3180 metres per second.
If your picture doesn't fully show the question and they tell you what the distance is, then replace X with the correct distance.

Explanation:
The current from the battery always flows from the positive terminal of the battery to the negative terminal of the battery.
If we connect a red coloured wire to the positive terminal of the battery and black coloured wire to the negative terminal of the battery, and then reverses the wire to their respective terminals, then there is no change in the direction of flow of current. It does not matter that which wire is connected to the particular terminal. The current always flow from positive to negative terminal of the battery outside the battery.
Answer:
Yes
Explanation:
Accerelation is measured by change in velocity. So naturally, if an object is slowing down, its velocity is decreasing so acceleration is negative. If it is speeding up velocity is increasing so positive acceleration.
(Velocity final - Velocity initial)/t
Note that this does not apply only to gravity, but to all linear accelerations
