In takes Russel 20 minutes to inspect a car and Sohel needs 18 minutes to inspect a car. They both start inspecting cars separately at 8.00 A.M. At certain points of time, both of them will finish inspecting a car at the same time. When will this occur for the time?

The least common multiple of 20 and 18 is 180. So, they will finish inspecting cars 180 minutes after starting.
Now, 180 minutes = 3 hours
So, 8 am + 3 hours = 11 am.
