Answer:

270 portraits in 9 hours

Step-by-step explanation:

2 every 4 minutes

60/4 = 15 (4 minute  intervals in one hour)

15 x 2 = 30 portraits per hour

9 x 30 = 270
  • 2 protraits per 4 min
  • Rate per protraits=2min

Total 2 mins In 1h

  • 60/2=30

Total 2mins In 9h

  • 30(9)
  • 270

Total protraits=270
