Question

You set your stationary bike on a high 80 N friction like resistive force and cycle for 30 min at speed of 8 m/s. Your body is 10% efficient at converting chemical energy in your body into mechanical work. What is your internal chemical energy change? How long must you bike to convert 300000 J of chemical potential while staying at this speed?

I converted 30 min to 1800 sec
don't know what to do from there
