R. McNeill Alexander, a British paleontologist, uses observations of living animals to estimate the speed of dinosaurs. Alexander believes that two animals of different sizes but geometrically similar shapes will move in a similar fashion. For animals of similar shapes, their velocity is directly proportional to the square root of their hip height. Alexander has compared a white rhinoceros, with a hip height of 1.5 m, and a member of the genus Triceratops, with a hip height of 2.8 m. If a white rhinoceros can move at 45 km/hr, then what is the estimated velocity of the dinosaur?
