If you ate a SNICKERSTM bar that has 220 Calories, and you can burn off 1.84 horsepower when running stairs, how long in minutes would you h

Energy required = 220*1000*4.18 J

$${\mathtt{Energyrequired}} = {\mathtt{220}}{\mathtt{\,\times\,}}{\mathtt{1\,000}}{\mathtt{\,\times\,}}{\mathtt{4.18}} = {\mathtt{Energyrequired}} = {\mathtt{919\,600}}$$  Joules

Power available = 1.84*746 J/s

$${\mathtt{Poweravailable}} = {\mathtt{1.84}}{\mathtt{\,\times\,}}{\mathtt{746}} = {\mathtt{Poweravailable}} = {\mathtt{1\,372.64}}$$ Joules/second

Time = Energy required/(60*Power available) minutes

$${\mathtt{Time}} = {\frac{{\mathtt{919\,600}}}{\left({\mathtt{60}}{\mathtt{\,\times\,}}{\mathtt{1\,372.64}}\right)}} = {\mathtt{Time}} = {\mathtt{11.165\: \!831\: \!293\: \!468\: \!547\: \!2}}$$ minutes
