We are given displacement = 20 meters.
Time given = 4.7 seconds.
Velocity = 4.3 m/s.
Please note : Velocity is a vector quantity. A vector quantity depends on magnitude and direction as well.
We are given magnitude of displacement = 20 meter and time 4.7 seconds but the direction is missing there.
If it would be in forward direction it would be positive and if it would be in backward direction, it would be of negative. 
Therefore, <u>"B)the direction"</u> is correct option.

Answer:
45
Step-by-step explanation:
Since this is only three terms
Find the three terms and add
j=1   3(1)^2+1 = 3+1 =4
j=2   3(2)^2+1 = 3(4)+1 =13
j=3   3(9)^2+1 = 27+1 =28
The sum is 4+13+28 =45
 
        
             
        
        
        
7×10^7 = 70000000 (10^7 = 10000000)
