Reggie can line a football field in 120 minutes. rosalinda can line a football field in 80 minutes. if they work together, how many minutes does it take them to line a football field?

48 minutes

Step-by-step explanation:

Given that;

Rosalinda can line the football field in 80 minutes

Reggie can line the football field in 120 minutes

Lets assume that if they work together, they will take T minutes to line the football field

Hence;

Thus in 1 minute, Rosalina can line 1/80 of the field where as Reggie can line 1/120 of the field

The sum of the two fractions will represent the size of the field that can be lined in 1 minute.

The reciprocal of the sum of the two fractions will represent the time taken for both Rosalinda and Reggie to line the field.

Answer ; It will take them 48 minutes for them to line the football field
