total distance to be covered = 24 m
speed of truck ; 36 * 5/18 ; 10 m/s
relative speed = speed of car(x)- speed of truck
speed =distance / time

x-10=24/10
x=12.4 m/s
Option C

distance to overtake trailer:
4+20m=24m

convert speed km/hr to m/s:
36/1*1/60min*1/60sec*1000m/1=36000/3600=10m/s

relative rates same direction (subtract):
distance/(r1-r2)=10secs
24/x-10=10, 24=10x-100, x=124/10=12.4m/s
