Alex is 1.6 m tall and noah is 1.5 times as tall as alex. how much taller is noah in centimeters?

For this case we can represent the problem as a mathematical equation.
 Let
 x = height of Alex.
 y = height of Noah.
 The equation that best represents the problem is
 y = 1.5x
 Substituting Alex's height value
 y = 1.5 * (1.6) = 2.4
 y = (2.4m) * (100cm / 1m) = 240cm
 Then, the subtraction of both heights will result in how much higher Noah is
 240cm-160cm = 80cm
 answer
 Noah is 80cm taller than Alex
