In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.
Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.
Given is that an automated car wash can wash 30 cars in 5 hours.
Now, an automated car wash can wash 30 cars in 5 hours.
Then, 1 car can be washed in (5/30) hours.
So, 120 cars will take (5/30 x 120) hours
(5/30 x 120)
5 x 4
20 hours
Therefore, an automated car wash can wash 120 carsin 20 hours.
