there r three variables
a,b,c
so find their units in following eqn
v=at + b/t+c (t+c are in division wid b) (here a,b,c are variables..........v is velocity n t is time)

the units r...
a=LT*..(*=-2)
b=Lraised to power -1Traised to power2
c=T

v = at + b/(t+c)
now when two quantities are added, their dimensions should be equal to each other and to the other side of the equation.
so dimensionally
v == at
a ==v/t = L.T^-2
v == b/(t+c)
here again c and t are added so c has dimension T.
and now
v == b/T
so b = L (dimension)

a = LT-2
b=L
c=T
Rate, if useful.
