Which of the 2 scenario flights will result in a longer flying time, or will they fly the same Scenario 1. span of 0.225 m and a chord of 0.045 m with a weight of 0.0500 Newtons and the LER is 0.2025

Scenario 2. span of 0.245 m and a chord of 0.045 m. the weight is 0.0523 newtons. so the LER is 0.2108
