Answer:
6 days
Step-by-step explanation:
If Jenny and Keisha were both on the trail today, how many days until they are both on the trail again?
To determine the days until they are both on the trail again, find the lowest common multiples of 2 days and 3 days
Jenny runs 5 miles every 2 days on a local trail = 4, 6, 8, 10, 12
Keisha runs 5 miles every 3 days on the same trail = 6, 9, 12, 15,18
The lowest common multiple of 2 days and 3 days is 6 days
Therefore,
If Jenny and Keisha were both on the trail today, they are both on the trail again in the next 6 days
