Car B and E are speeding up, while car C is slowing down.
Step-by-step explanation:
Acceleration (a) is the rate of change of velocity with time.It is calculated by dividing the change in velocity (Δv) with the time taken for the change to occur.In this question , the time is 10 sec in all cases.You divide the velocity in km/h by 3.6 to convert to m/s
In Car A
Δv=8.33-8.33=0m/s
t=10s
a=0 m/s² ⇒car is moving with same speed and in the same direction
Car B
Δv=5.55-0=5.55
t=10
a=5.55/10 =0.555 m/s² ⇒car is speeding up
Car C
Δv = 0-8.33= -8.33 m/s
t= 10
a= -8.33/10 = -0.833 m/s² ⇒car is slowing down
Car D
Δv= 0-0 =0
t=10s
a=0/10 =0 m/s² ⇒car is at rest
Car E
Δv = 8.33-5.55=2.78
t=10
a=2.78/10 = 0.278 m/s²⇒car is speeding up

Answer:
I think the answer is 43.8
Hey there! :)
The first arrow is on 2. That means the expression starts with 2.
You can cross out the last choice
The second arrow is on -1. That means the answer is -1
The correct choice is C.
Hope this helps :)
Answer:
7 or 6^7
Step-by-step explanation:
.1 repeating is 1/9, so either write it as 12 1/9, or 109/9
