The local gym holds two 45-minute workout sessions and four 30-minute sessions each week. Judy attended all of the sessions this week but left 5 minutes early during the 30-minute sessions and 10 minutes early during the 45-minute sessions. How many total minutes did Judy work out for the week?

Answer:

280 minutes

Step-by-step explanation:

2 x 45 = 90

4 x 30 = 120

2 + 4 = 6 (because Judy left 5 minutes early every class)
6x5 = 30 min

90 + 120 = 310

310 - 30 = 280min

Answer:

170 minutes

Step-by-step explanation:

first let's begin by finding how many minutes are the local gym sessions

(45·2) + (4· 30)

90 + 120

210 minutes

now Judy left 5 minutes early during all the 30-minute sessions now this is where the most common mistake lies there was four sessions, so we have to multiple 5 with 4

5 · 4 = 20

And Judy also left 10 minutes early during all the 45-minute sessions   there were two 45- minute session, so we have to multiply

10 ·2 = 20

now let's add the two products together

20 + 20 = 40

40 minutes

now subtract the total minutes from her leaving early minutes

210-40

170 minutes
