Area under a velocity-time graph represents distance. You're told that distance = 800m. The two trapezia have the same area. You know how to calculate area hopefully, so apply your knowledge on that to get the two equations.

In a velocity-time graph, the area represents distance travelled.
The distances are calculated as areas of trapeziums.
So we have two equations = 800

Oh yeah, I didn't even notice that, I was thinking too much about the suvat equations. Thank you
