WebFrom the definition that work = force x distance, simply rearrangement gives distance = work/force. If all 40 million J of energy in 1 L were used to do the work of overoming the air resistance and frictional forces, the distance would be: Distance = work ÷ force = 40,000,000 ÷ 500 N = 80,000 m/L = 80 km/L.
