All of the members of our spray-painting team paint at the same speed. If 8 team members can paint a 5000 square foot wall in 30 minutes, then how many minutes would it take the 8 members to paint an 8000 square foot wall?
The Team paints at a rate of 5000 sq ft / 30 min = 166.67 sqft/min
Since the team does not change size:
8000 sq ft / 166.67 sqft/min = 48 min
