Question

In a biology course, students spend a total of 295 minutes in lab and lecture each week. The lab time is 65 minutes shorter than the lecture time. How many minutes do the students spend in lecture and how many minutes do students spend in lab per week?

Answer 1

Set the lecture time to x and the lab time to x - 65

The time in both the lecture and lab add up to 295 minutes, so

x + x - 65 = 295

2x = 360

x = 180 (lecture)

180 - 65 = 115 (lab time)

So the students spent 180 minutes in lecture and 115 minutes in the lab
