The variation of velocity of a particle with time moving along a straight line is illustrated in the following figure. The distance travelled by the particle in four seconds is.........$m$
Distance = Area under $v -t$ graph $ = {A_1} + {A_2} + {A_3} + {A_4}$
$ = \frac{1}{2} \times 1 \times 20 + (20 \times 1) + \frac{1}{2}(20 + 10) \times 1 + (10 \times 1)$
$ = 10 + 20 + 15 + 10 = 55\;m$
