C is the answer .
V=5+8t , where t is the time
That is v=5+8*5
V=45 ms-1
V=5+8t , where t is the time
That is v=5+8*5
V=45 ms-1

Answer:-
(c) is the correct option.
Given:-
We have,
v = 5+8t
And time, t = 5s
To find:-
Velocity after 5seconds.
Solution:-
Put the value of time in the given equation, we get,
v = 5+8(5)
= 5+40
= 45
