    Arunner has the power of 400 W as they run, how much chemical energy do they convert into other forms in 10 minutes?

    Power = work or energy/time

    time = 10 mins = 10x60 = 600 seconds

    400 = energy/600

    energy = 400 x 600

    energy = 240000 Joules

    therefore the chemical energy needed is 240,000 joules
