<span>Hot springs and geysers are often found in areas of present or past volcanic activity. The hot spring forms when water deep underground is heated by a nearby body of magma or hot rock. The hot water rises and collects in a natural pool; when rising hot water and steam become trapped in a narrow crack, pressure builds until the mixture sprays above the surface as a geyser.</span>

Answer:
17.27m/s
Explanation:
M1U1 + M2U2 = (M1+M2)V
(900x15) + (750 x 20) = (900+750)V
13500+15000 = (1650)V
28500 = 1650v
V = 28500/1650 = 17.27m/s
V = 17.27m/s
