The train station clock runs too fast and gain seven minutes every 4 days how many minutes and seconds will have gained at the end of ten days

Answer :

[tex]\bf \begin{array}{ccllll} minutes&days\\ \textendash\textendash\textendash\textendash\textendash\textendash&\textendash\textendash\textendash\textendash\textendash\textendash\\ 7&4\\ x&10 \end{array}\implies \cfrac{7}{x}=\cfrac{4}{10}[/tex]

solve for "x" to see how many minutes,

if you get a decimal amount, like 2.17, multiply the .17 times 60
to get the seconds

or do it in seconds

[tex]\bf \begin{array}{ccllll} seconds&days\\ \textendash\textendash\textendash\textendash\textendash\textendash&\textendash\textendash\textendash\textendash\textendash\textendash\\ 420&4\\ x&10 \end{array}\implies \cfrac{420}{x}=\cfrac{4}{10}[/tex]
