Question

Two cars A and B are moving in same direction with the speed 10 m/s and 8m/s respectively. If both cars start from the same point, then distance between cars A and B after 1 minute will be​

Answer 1

Answer:

Explanation:

Let distance covered by A be S  1

​

 

Let distance covered by B be S  2

​

 

B will catch A when S  1

​

=S  2

​ S=ut+1/2×a×t  2

 

Therefore from given data,

40t+(1/2×0×t  2  )=0t+1/2×4×t  2

 40t=2t  2

 

20t=t  2

 

t=20s
