Answer:
1 mi = 5280 ft * 12 in/ft = 63360 in
A convenient conversion factor (to remember) is 1 m = 39.37 in
63360 in / (39.37 in / m) = 1609.3 m
26 mi + 285 m = 26 * 1609.3 + 385 = 42,228 m
(a) As the car is moving with constant velocity, it means the rate change of velocity does not change, therefore the average acceleration of the car is zero.
Thus, there is no acceleration, when velocity is constant.
(b) Average acceleration,

Here, v is final velocity and u is the initial velocity and
is the time interval.
As twelve seconds later, the car is halfway around the track and traveling in the opposite direction with the same speed, therefore

Thus, the average acceleration of the car is
in the direction to the left.
A statement which describes the changes that occur in this sequence of events is: 2. matter is converted into energy and then energy is converted into matter.
<h3>What is the law of conservation of matter?</h3>
The law of conservation of matter (LOCOM) states that mass can neither be created nor destroyed in any chemical reaction.
Similarly, the energy possessed by a matter can neither be created nor destroyed, but it can only be converted from one energy form to another.
In this context, we can logically deduce that a statement which best describes the changes that occur in this sequence of events is that matter is converted into energy and subsequently, energy is converted into matter.

All you have to do is multiply that by the mass or volume.
