Answer: 5.43 minutes
Step-by-step explanation:
Number of minutes for the drama group = 90 minutes
Number of times to practice the pirate scene = 4
Time taken to practice the pirate scene = 13
The number of minutes used for pirate scene will be:
= 4 × 13 = 52 minutes
The number of full times that the group can practice the mermaid scene will then be:
= (90 - 52) / 7
= 38 / 7
= 5.43 minutes
