Final answer:
The runner converts 6000 joules of chemical energy in 10 minutes.
Step-by-step explanation:
To determine the chemical energy converted, we need to use the formula Energy = Power x Time. Given that the runner's power is 600 watts and she runs for 10 minutes, we can calculate:
Energy = 600 watts x 10 minutes = 6000 joules.
Therefore, the runner converts 6000 joules of chemical energy in 10 minutes.
