Answer:
Man speed = 6km/h = 100m/min
Man speed = 6km/h = 100m/minSince both car and man were moving so relative speed = 450m/4.5min
Man speed = 6km/h = 100m/minSince both car and man were moving so relative speed = 450m/4.5minLet assume car speed be x
Man speed = 6km/h = 100m/minSince both car and man were moving so relative speed = 450m/4.5minLet assume car speed be xSo,
Man speed = 6km/h = 100m/minSince both car and man were moving so relative speed = 450m/4.5minLet assume car speed be xSo,x-100 = 450/4.5
Man speed = 6km/h = 100m/minSince both car and man were moving so relative speed = 450m/4.5minLet assume car speed be xSo,x-100 = 450/4.5Or, x = 200
Man speed = 6km/h = 100m/minSince both car and man were moving so relative speed = 450m/4.5minLet assume car speed be xSo,x-100 = 450/4.5Or, x = 200so Speed of car = 200m/min = 12km/h

Answer:
Let's car speed xkmph
Man speed 6kmph
Rs=(x-6)kmph "same direction
Rd=450/1000=45/100km
Time=4.5/60H
4.5/60=45/100**(x-6)
6=x-6
X=6+6=12kmph Ans.
