Answer:
Acceleration : 1.8 km/hr^2 , Distance : 450 km
Explanation:
Acceleration - final velocity - initial velocity / time taken . (SI unit of acceleration is m/s^2 or km/hr^2
54-36 = 18 /10 = 1.8 km/hr^2
using second equitation of motion
s = ut + 1/2 at^2
36*10+1/2*1.8*10*10
360+90
450 km = Distance
