folding or tilting of rock layers, followed by renewed deposition.

The answer would be:
<u><em>B. Acceleration is a vector quantity.</em></u>
We can rule out the others because:
---Acceleration CAN be described with a negative number. The sign actually shows the direction. A negative number indicates a deceleration.
---Displacement change over time is the definition of velocity NOT acceleration.
---The SI unit for acceleration is m/s².
***A <em>vector quantity</em> is measure of <u>magnitude</u> and <u>direction</u>, which acceleration has.
Use this to help you. So here velocity is not given… so we have to calculate velocity of the car from given data. Car travel 60 km in 35 minutes. Frist of all we have to convert 35 minutes in hours by deviding 35 to 60 hour = 35/60
Next we have to calculate distance in kilometres so distance =velocity ×time.
Velocity =distance / time
Velocity =60/(35/60)
Velocity=3600/35
Distance = velocity ×time
In one hour… it will travel…
Distance =(3600/35) ×1.
By dividing you will get the answer…hope it will
