The length of runway=80m/s * 35s=2800 m

relies upon if the acceleration is consistent. I it ISNT you CANT calculate a minimum. even if that's is consistent ish acceleration then the avearge velocity may be envisioned as 40 m/s for 35 seconds provides 1400 m

Average speed is 40m/sec * 35sec = 1400m
