Question

The length of a long rod is measured first by using a pace span and then, by using the foot span of a person. For the person, the length of one pace-span is four times the length of one foot-span. If the length of the rod is $6$ pace-spans, then what is the length of the rod in terms of foot span?

Answer 1

Length of rod in terms of foot span :

Since the length of one pace-span is four times the length of one-foot span.

$\begin{array}{rcl}\because \mathrm{One}\mathrm{pace}\mathrm{span}& =& 4\times \mathrm{one}\mathrm{foot}\mathrm{span}\\ \therefore 6\mathrm{pace}\mathrm{span}& =& 6\times 4\\ & \Rightarrow & =24\mathrm{foot}\mathrm{span}\end{array}$

Hence, the length of the rod is $24$ foot span.
