The element of a valid contract which is established by getting the signatures of all parties is <u>mutual agreement</u>
<h3>What is an element of a valid contract?</h3>
An element of a valid contract simply refers to that promise made between two or more parties that which allow the courts to make judgement. 
Some elements of valid contract are: 
- Offer
- Acceptance
- Consideration
- Intention to create legal relation
- Certainty and capacity.
So therefore, the element of a valid contract which is established by getting the signatures of all parties is mutual agreement

Car  A will have highest speed is 83.3m/s . 
<h3>What is speed ? </h3>
The rate of change of position of an object in any direction. 
The S.I unit is m/s . Speed is a scalar quantity it defines only magnitude not direction
 . 
speed = distance /time 
In case of Car A , 
We have given distance 150Km in 3 min , 
First we have convert the distance km to m 
150×1000m 
then conversion of min to sec 
  38×60sec 
speed = 15000/180 
speed = 83.3m/sec 
In case of Car B 
we have given 800m in 150 min 
lets convert the time into second 
150×60 
Speed = 800/150×60 
speed = 0.88m/ s 
In case of Car C 
We have given here distance 250 Km and time in 8 hours 
convert km to m 
25000 
and time into sec 
88×60×60 
speed = 0.86m/ s
Hence ,Car A has highest speed amongst them .

Answer:
Final velocity (v) = 36 m/s
Distance traveled (s) = 2,160 m
Explanation:
Given:
Initial velocity (u) = 0
Acceleration (a) = 0.3 m/s
Time travel (t) = 2 minutes = 120 seconds
Find:
Final velocity (v) = ?
Distance traveled (s) = ?
Computation:
v = u + at
v = 0 + 0.3(120)
v = 0.3(120)
v = 36 m/s
Final velocity (v) = 36 m/s
Distance traveled (s) = ut + (1/2)at²
Distance traveled (s) = (0.5)(0.3 × 120 × 120)
Distance traveled (s) = 2,160 m
