What is the minimum amount of time required to perform all five activities?

Answer:
7 hours or 420 minutes.
Step-by-step explanation:
0.5 = 30 minutes
1.0 = 60 minutes
2.0 = 120 minutes
1.5 = 90 minutes
2.0 = 120 minutes
= 420 minutes
Every hour is 1.00 so 0.5 would be 30 minutes. I'll allow you to add up the time now.
