After 270 seconds, both cars will meet again at the startingpoint.
To find the time at which both cars meet again at the starting point, we need to find the least common multiple (LCM) of their lap times. The LCM is the smallest positive integer that is divisible by both lap times.
David's car lap time = 90 seconds
Chris' car lap time = 54 seconds
Now, let's calculate the LCM:
Find the prime factors of each lap time:
90 = 2 × 3² × 5
54 = 2 × 3³
Take the highest power of each prime factor:
LCM = 2 × 3³ × 5
= 2 × 27 × 5
= 270 seconds
So, after 270 seconds, both cars will meet again at the startingpoint.
