Answer:

170 minutes

Explanation:

Weekly gym sessions:

  • Two 45-minute workout sessions.
  • Four 30-minutes sessions.

Therefore, the total time for all sessions is:


\begin{aligned}\implies \sf Total\:time & = \sf 2 * 45 + 4 * 30\\& = \sf 90 + 120 \\& = \sf 210 \:\:minutes\end{aligned}

If Judy attended all sessions, yet

  • left 10 minutes early during the 45-minute sessions, and
  • left 5 minutes early during the 30-minute sessions.


\begin{aligned}\implies \sf Total\:time\:Judy\:lost& = \sf 2 * 10 + 4 * 5\\& = \sf 20 + 20 \\& = \sf 40\:\:minutes\end{aligned}

Therefore:


\begin{aligned}\implies \sf Total\:time\:Judy\:worked\:out & = \textsf{Total time of sessions}-\textsf{Total time Judy lost}\\& = \sf 210-40\\& = \sf 170\:\:minutes\end{aligned}

So Judy worked out for a total of 170 minutes for the week
