A biotechnology project manager in Atlanta has 240 student participants in a lab-grown food trial. One-third are high school freshmen, half are sophomores, and the rest are juniors. Each group spends 45, 60, and 75 minutes respectively in the lab. What is the total number of lab hours spent by all students?

**How Much Lab Time Do Students Spend in Atlanta’s Historic Lab-Grown Food Trial?** Amid growing interest in sustainable food sources and youth engagement in cutting-edge biotechnology, a recent lab-grown food initiative in Atlanta has captured attention—featuring 240 high school students in a hands-on scientific trial. With participants divided into freshmen, sophomores, and juniors, each spending 45, 60, and 75 minutes in the lab respectively, the collective investment of time reveals compelling trends in youth participation and STEM education. **The Student Mix and Engagement Levels**
A biotechnology project manager in Atlanta recently launched a lab-based food innovation project involving 240 high school students. Freshmen (exactly one-third, or 80 participants) spent an average of 45 minutes in the lab—likely focusing on foundational procedures and team collaboration. Sophomores (50% of participants, or 120 students) dedicated 60 minutes, balancing experimentation with data recording. Juniors (the remaining 20%, or 48 students) spent the longest—75 minutes—engaging deeply with advanced techniques and project facets. **Total Lab Hours Explained**
To calculate the total lab time, convert each session’s duration to hours and multiply by group size. Freshmen contributed: 80 × (45/60) = 60 lab hours. Sophomores contributed: 120 × (60/60) = 120 lab hours. Juniors contributed: 48 × (75/60) = 60 lab hours. Adding these gives a grand total of 240 lab hours—equivalent to 40 full workdays of hands-on student time.
