Help me with this problem. Brett usually takes 50min to groom the hores. After working 10 min, he was join by angla and they finished the grooming in 15min. How long would it have taken Angela working alone?

    In 10m, Brett had finished 20% of the job. In the next 15m, he finished another 30%, for a total of 50% of the job. Angela finished the other 50% of the job in 15m, so she would've taken 30m by herself. BTW, I assume you meant 'horse', not what you actually typed ;)
