Question

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?

170 minutes

190 minutes

65 minutes

75 minutes

Answer 1

170 minutes

Explanation:

number of 45-minute sessions = 2

number of 30-minute sessions = 4

Since Judy left 5 minutes early each 30-minute session, each 30 minute session became 25 minutes. (30 - 5 = 25)

4 × 25 minutes = 100 minutes

Since Judy left 10 minutes early each 45-minute session, each 45 minute session became 35 minutes. (45 - 10 = 35)

2 × 35 minutes = 70 minutes

total time = 100 minutes + 70 minutes = 170 minutes
