Title: Rate problems containing fractions Post by: SIN on Apr 11, 2018 A small hydroelectric generating station can produce 61 gigajoules (GJ) of energy per year. After 4.0 months of operation, another generator is added which, by itself, can produce 39 GJ in 5.0 months. How many additional months are needed for a total of 95 GJ to be produced?
