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.

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.
