Wilma can mow the lawn in 4 hours. If Kyle helps her with another mower, the lawn can be mowed in 3 hours. How many hours would it take Kyle if he worked alone?

12 hours

Step-by-step explanation:

Let w = Wilma alone

Let k = Kyle alone

Let t = Working together

Given the following data;

Time it took Wilma = 4 hours

Time it took them together = 3 hours

Time it took Kyle = x

To find the time it will take Kyle, we would use this arithmetical expression;

Substituting into the equation, we have;

Lowest common denominator (LCD) = 12x

Multiplying all through by "12x" we have;

Simplifying the equation, we have;

Rearranging the equation, we have;

x = 12 hours.

Therefore, it would take Kyle 12 hours to mow if he worked alone.
