Answer:
40 minutes
Step-by-step explanation:
We simply want to find the least common multiple (lcm) of the two times (5 and 8). Which is 40 minutes
For a more visual representation every 5 minutes Georgia will cross the starting line while it will take Susana 8 minutes to cross after starting at the same time.
So Georgia will cross at (5, 10, 15, 20, 25, 30, 35, 40) minutes
While Susana will cross at (8, 16, 24, 32, 40) minutes
First you need to give both fractions a common denominator lets say 40. So N would be 8/40 and Z would be 35/40, so Z collected more than N. All together they collected 43/40 which simplifies to be 1 and 2/40 which would again simplify to 1 and 1/20.
son 30 y si sumas con 20 son 96
