To train for a race Nathan bikes every two days in swims every five days he biked on October 2 and he swim on October 5. When is the first time Nathan will bike and swim on the same day.

Answer 1

We are given that Nathan bikes every two days and swims every five days.
Since Nathan biked on October 2, the next time he will bike would be on October 2 + 2 days = October 4.
Similarly, since Nathan swam on October 5, the next time he will swim would be on October 5 + 5 days = October 10.
Therefore, the first time Nathan will bike and swim on the same day would be on October 10.
