a= (v - u)/ t.. this might help..

k, so t = 5 min..
a= 0.2, u = 0 and v = ??
so, 0.2 = (v-0)/ (5* 30)
v = 150 * 0.2
V = 75 m /s..

k, so t = 5 min..
a= 0.2, u = 0 and v = ??
so, 0.2 = (v-0)/ (5* 60)
v = 300 * 0.2
V = 150 m /s..
this is right

x = ut + 1/2 * at2..

x = 0.5*0.2*(300^2)= 9000m

@Rohangrr : what exactly u want ??
speed = 60m/s and distance traveled in 5 min = 9000m... at uniform acceleration of 0.2 m/s2
