Question

Yuto and Riko went for a bike ride on the same path. When Riko left their house, Yuto was 5.25 miles along the path. If Yuto’s average speed was 0.25 miles per minute and Riko’s average speed was 0.35 miles per minute, then Riko will be behind Yuto when 0 ≤ t < 52.5, where t is time in minutes. Explain what this solution means and why t cannot be less than zero.

Answer 1

At least for the purposes of this problem, can time be negative?

And for explaning the solution, just convert the symbols to words.
"then Riko will be behind Yuto when 0 ≤ t < 52.5

...then Riko will be behind Yuto between the start of recording time and at 52.5 seconds
