We know that it would take Mabel 20 minutes to edit a 15-minute-long video by solving simple mathematical operations.
An operation, in maths, is a mathematical function that converts zero or more input values into a precisely defined output value.
The arity of the operation is decided by the number of arithmetic operations.
Most people seem to agree that addition, subtraction, multiplication, and division are the four basic mathematical processes.
So, what time it will take Mabel to dit a 15-minute long video:
Time to edit 15 min videos = New video * Total time taken/Length of added video
Time to edit 15 min videos = 15 * 4/3
Time to edit 15 min videos = 5 * 4
Time to edit 15 min videos = 20
Therefore, we know that it would take Mabel 20 minutes to edit a 15-minute-long video by solving simple mathematical operations.
