The question is incorrect and so got a wrong answer. Acceleration cannot be measured in m sec but m sec-2. The previous answerer, assumed that the questioner had meant velocity, not acceleration. If the velocity had been 2 m sec-1 then the time would have been 15 seconds. But it was not even m sec-1! It seemed the units were wrong.
If you assume that acceleration = 2 m sec-2 then
t2 = 2s/a = 2*30/2 = 30
and so
t = sqrt(30) seconds = 5.48 seconds (approx)

What is the effect of force on bodies at rest?
The force accelerates the body, a=F/m.
A car accelerates from rest and accelerates at 3 ms-2 how long it will take to reach a velocity of 30ms-1?
Acceleration = (change in speed) / (time for the change)3 = (30) / (time)3 x (time) = 30time = 30/3 = 10 seconds
