Question

A child has maximum walking speed of 1.6 m/s. What is the length of the child's legs?

0.26 m

Answer 1

speed = 1.6 m/s

need to know how many steps/s

then we can calculate how long each step is

with the angle between the 2 legs known

then we can calculate the length of legs.

Answer 2

There's not enough information in the question to calculate the answer.

Knowing the child's walking speed, we would need to know how often s/he takes a step in order to calculate the length of their legs.
