Distance = area under the graph
Using the trapezium rule, Area = 1/2 x (24+18) x 3 = 21 x 3 = 63m

Distance travelled will be = 63 m

What is equation of motion?

These are the equations that describe the behavior of a physical system in terms of its motion as a function of time .

Given : u = 24 m/s

           v= 18 m/s

           t = 3sec

using equation of motion : v = u + at

                         18 = 24 + a*3

                         -6 = 3a

                          a = -2 m/s^2

using equation of motion : s =  u t + 1/2 a (t^2)

                           s = 24 * 3 + 1/2 * (-2)(9)

                          s = 63 m
