Slow pipe rate = jobs per hour
Fast pipe rate = jobs per hour
Slow plus Fast pipes at same time rate = jobs per hour

The rates for each pipe are additive while they both work simulteneously. Solve first for t based on that. You can then know the rate for the slow pipe and can easily compute the rate for the fast pipe.
