Two balls are dropped to the ground from different heights.The second ball is dropped 3s after the first ball and both strike the ground at the same time. If the first ball took 6s to reach the ground,then the difference in the respective heights from which the two balls were dropped? (g=10m/s^(2))

Two balls are dropped to the ground from different heights. One ball is dropped 2 s after the other but they both strike the ground at the same time. If the first ball takes 5 s to reach the ground, then the difference in initial heights is (Take "g = 10 m s"^(-2) )
