Lana is watching Andrew and Rob race electric cars around a track. Andrew's car can go around the track in 8 seconds. Rob's car can go around the track in 6 seconds.

If the cars start at the same time, how many seconds will it take for both cars to cross the finish line together for the first time?

Answer :

Final answer:

Rob's car is faster than Andrew's car because it takes less time to complete a lap around the track.

Explanation:

In this scenario, Andrew's car takes 8 seconds to complete one lap around the track, while Rob's car takes 6 seconds. Since Rob's car completes a lap in a shorter amount of time than Andrew's car, it means that Rob's car is faster.
