Answer:
F= MASS *ACCELERATION
12=6*a
a=2 m/sec^2
v^2-u^2=2*a*s
v^2=2*2*3
v=sqrt(12)
v=3.5 m/sec
work done by force= change in kinetic energy
F*S=0.5*M*U^2-0.5*M*V^2
12*3=0 0.5*6*V^2
V=3.46 M/SEC
Explanation:

Speed = (distance covered) / (time to cover the distance)
Speed = (1,000 meters / 8.6 minutes) x (1 minute / 60 seconds) = 1.94 m/s
(rounded)
