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
