Problem

A cyclist starts from rest, accelerates uniformly at

1.2\,\text{m/s}^2

for

10\,\text{s}

, then travels with the obtained speed for

20\,\text{s}

, and finally brakes uniformly to rest in

5\,\text{s}

. The total displacement covered by the cyclist is closest to a)

390\,\text{m}

300\,\text{m}

360\,\text{m}

330\,\text{m}
