    For Nathaniel, he needs 75 min to finish the job. That is in 1 minute, he finishes 1/75 part of the job, right? Same as Brenda with 1/25 so that in 1 minute, both them will finish \(\dfrac{1}{75}+\dfrac{1}{25}= \dfrac{4}{75}\) part of the job. Summary: 1min------------4/75 ? min-----------75/75??

    nope 75/4 = 72 minutes + 3/4 minutes. That is 72minutes 45seconds

    `Nathaniel can weld a railing in 75 minutes. Brenda can weld a railing 25 minutes faster.` That means Brenda can finish the work in `50` minutes right ?

    so we must be solving \[\dfrac{1}{75}+\dfrac{1}{50} = \dfrac{1}{x}\]
