1. The problem statement, all variables and given/known data An automobile gets 20 miles per gallon when traveling at 60 miles per hour. With the energy content of gasoline at 36,000 watt-hr per gallon, convert this amount of power into watts. 2. Relevant equations W h (watt hours) | ([length]^2 [mass])/[time]^2 | energy W (watts) | ([length]^2 [mass])/[time]^3 | power Energy = Power (60) * time (3) = 60 x 3 = 180 Wh 3. The attempt at a solution If watt-hrs and watts are not compatible how am I supposed to convert these?
