a car on a straight level road is stopped for a red light.on a green light it uniformly accelerates to a velocity of 18m/s in 3 minutes.what is its acceleration?

Acceleration has a unit of
m/s².
from 0 to 18m/s in 3 minutes</>
is the same as
0 to 18 m/s in 180 seconds, which translates to
18m/s / 180 seconds
or
0.1 m/s²
A bicycle does better than that, haha!
