Question

Two cars A and B at a distance 1km are moving in a direction. Car A is moving with the speed of 20 m/s and car A is chasing car B in 100 sec. Find speed of car A.

Answer 1

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
