Would I solve to problem using the displacement formula?

d = 1/2 *a* change in time ^2 + vi * change in time

The speed of Tractor is 2 m/sec.

The length of the field is 750 m.

Displacement S = ut + (0.5)at²

Here the accerlation (a) is unknown, so we make use the following formula.

Speed = Distance / time

time = Distance / Speed

time = 750 / 2

time = 375 sec.

time t = 6 mins 15 sec.

Therefore time taken by the tractor to travel a 750 m is 6 mins 15 seconds.
