Abus starting from rest moves with a uniform acceleration of 0.1 ms ^-2 for 2 minutes. find the speed acquired then find the distance travelled

1) Speed acquired
The time taken for the motion is

The bus is moving by uniformly accelerated motion, with constant acceleration , so the speed acquired by the bus after 120 s is


2) The distance traveled is given by the following formula:

where a is the acceleration and t the time. Substituting numbers into the equation, we find

Independent variable is something that is changed in a experiment.
