It takes susana 8 mins to walk the track. Her friend Georgia runs the track every 5 mins. When will they be at the starting line at the same time

Respuesta :

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
