v(t)=v0+a*t
So v(5)=4.3+3*5=19.3 m/s
 
d(t)=v0*t+a*t2/2
 
d(5)=4.3*5+3*52/2=21.5+37.5=49 m

Hello again, Sun -- here's the "play-by-play" ... the speed stair-steps 4.3, 7.3, 10.3, 13.3, 16.3, 19.3m/s at 5sec ... ave speed is 11.8 m/s running for 5 sec ==> displaces 55 +4 or 59m :)
V = Vo + at = 4.30 + 3.00*5.00 = 19.30 m/s
d = Vot + (1/2)at^2 = 4.30*5.00 + (1/2)(3.00)(5.00)^2 = 59.00 m
or
d = (1/2)(Vo+V)t = (1/2)(4.30+19.30)(5.00) = 59.00 m
