Question

Jake stands in an elevator. As the elevator speeds up departing the 1st floor, and then slowing down approaching 11th floor, Jake feels his weight first increasing, then decreasing. The magnitude of the acceleration of the elevator is the same 3.7 m/s2 in both cases (but the direction is different). If Jake feels 307.4 N heavier when he is departing the 1st floor, than when he is approaching the 11th floor, then what is his true weight? (Weight should be in Newtons)

Please try to give me the correct answer. with well written work.
