The area under a velocity time graph is distance travelled (as integrating velocity gives distance), so we can imagine the v/t as a line, giving a triangle with 2 sides of 13.8 and 18. The area of a triangle is bh/2, so 9*13.8 = 124.2m which is how far the car travelled in that time.
60.8cm is 0.608m, and now we can divide to work out the number of revolutions:
124.2/0.608 = 204.28 = 204 revolutions to 3sf (number of sf in the question assuming 18 is in fact 18.0, so the number you should give your answer to)

Answer:
final speed is (3.5 + 1.5) = 5 m/s
Explanation:
If it accelerates for 3 seconds with 0.5m/s² What will be the new speed?
An acceptation of 0.5 m/s² means that every second the speed increases by 0.5 m/s. After 3 * seconds you gain in speed by 3 * 0.5 = 1.5 m/s So the final speed is 3.5 + 1.5 = 5 m/ s
Here is another method:
u =3.5m/s
Make use of
a = (v-u) / t
where:
a is acceleration in m/s² =0.5
v is final velocity in m/s = ?
u is initial velocity in m/s = 3.5
t is time in s = 3
Rewrite so it starts with v =....
a = (v)/t - (u) / t
v/t = u/t + a
multiply left and right of the = sign by t
v = u + a * t
Substitutie the known numbers
v = 3.5 + 0.5 * 3
final speed is (3.5 + 1.5) = 5 m/s
Quality research most commonly refers to the scientific. process encompassing all aspects of study design; in. particular, it pertains to the judgment regarding the match. between the methods and questions, selection of subjects, measurement of outcomes, and protection against.
