Answer:
30 m/s
Explanation:
in the question speed of car ' B' be
20 m/s
speed of car B = 20 m/s
distance between A and B =1km=1000 m
car A chases car B in 100 s
Distance travelled by car B un this time
=(20×100)m=2000m
initially car A is 1000m away from Car B
therefore car A covers (2000+1000)m
=3000m in 100s
Speed of car A =3000/100=30 m/s
