In a science contest, 30 students will present their science projects. Each student gets to talk for 20 minutes. How much time is needed to present all of the science projects? (1 point) Responses 600 minutes 600 minutes 1,800%C2%A0minutes 1,800%C2%A0minutes 50%C2%A0minutes 50%C2%A0minutes 610%C2%A0minute
To present all 30 science projects, we need to multiply the number of students by the time each student gets to talk: 30 students * 20 minutes/student = <<30*20=600>>600 minutes.
Therefore, the correct answer is 600 minutes.
