<human>:  The base of a hill located beside a river is 300m above the seabed. If this depth is a quarter of the vertical distance between the riverbed and the peak of the hill, how high is the hill?
<bot>: How far is the riverbed from the hill's peak? ** 300m is a quarter of the distance from the riverbed to the hill's peak so (1/4)*distance from riverbed to peak = 300m
How far is the riverbed from the hill's peak? ** Multiplying both sides of the equation by 4 gives the distance from riverbed to peak = 300m*4 = <<300*4=1200>>1200m
How high is the hill? ** The height of the hill is the difference between the distance from the riverbed to the hill's peak and the distance from the riverbed to the hill's base which is 1200m-300m = <<1200-300=900>>900m
