Constants

On flat ground, a $70-kg$ person requires about $300$ W of metabolic power to walk at a steady pace of $5\mathrm{.}0k\frac{m}{h}(1\mathrm{.}4\frac{m}{s}).$ Using the same metabolic power output, that

Based on these data, how does the energy used in biking $1$ km compare with that used in walking $1$ km $?$ Biking takes person can bicycle over the same ground at $10k\frac{m}{h}.$

$2$ times the energy of walking the same distance.

$4$ times the energy of walking the same distance.

the same energy as walking the same distance.

$\frac{1}{2}$ of the energy of walking the same distance. $$
