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. if they both start at the same time after how many seconds will they be side by side again ?

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.
