Question

Suppose your body was able to use chemical energy in gasoline. How far could you pedal a bike at 15 km/hr on energy of 1 gal of gas?

I'm having trouble finding the answer to this question but I am also having trouble with the assess questions listed below. If you could please help me solve those as well, that would be great. Thank you!

Assess C1: Discuss the result by comparing distance you'll be able to cycle with energy of 1 gal. of gas with the distance you'll be able to cover by driving a car.

Assess C2: What is the efficiency of typical standard car and efficiency for human cycling in %?

Assess C3: Describe what food calorie is and what is the equivalent value in joules?

Answer 1

Now, about the assess questions

(1) Generally the regular cars that we have in US give an efficiency 20 miles per gallon. i.e., 32 km

(2) Typically the efficiency of car is ~ 30%

bicycle is nearly 80 times more efficient than a car.

(3) A food calorie is the base unit to measure energy. 1 calorie = 4.184 Joules of energy.

I hope you will find the answers useful. Please rate. Cheers.
