Answers
Answer:
It Depends on the traffic
Explanation:
If It took 1 hour then,
1 hr x 6000 calories per minute
60 x 6 kcal
360 kcal
360000 calories
Answer:
A reasonable average is 5 km per kWH. Since a kWH is 3.6 MJ, this means about 720 kJ per km.
A reasonable estimate of the absolute minimum energy is to assume no air friction (moving very slowly) and having only rolling friction. At 2% rolling friction, the minimum comes out at about 200 kJ. If the electric motor drive is 60% efficient, you still need about 350 kJ of electric power.
If you have a gasoline engine that is 25% efficient, the average of 720kJ per km corresponds to 0.08 liters of gasoline per km. That works out to 33 mpg in US measures.
To sum up:
Average ——————- 0.2 kWH ——720 kJ —— 80 ml gasoline
Absolute minimum — 0.1 kWH ——360 kJ —— 40 ml gasoline
