We'll take out LCM of 24 seconds and 28 seconds.
that is, 168 seconds.

That means,
Car A and Car B will be side by side to each other after 2 mins 48 seconds after start.

Answer:

After 168 seconds, both the cars will be side by side again.

Step-by-step explanation:

On a track for remote controlled racing cars racing car A completes the track in 28 seconds while racing car B completes it in 24 seconds.

To know after how many seconds will they be side by side again, we will find the LCM of 24 and 28.

24 = 2 x 2 x 2 x 3

28 = 2 x 2 x 7

LCM is = 2 x 2 x 2 x 3 x 7 = 168

Hence, after 168 seconds, both the cars will be side by side again.
