time taken by 45 people = 5 hours

→ time taken by 45 people = 300 minutes

→ time taken by 1 people = 300 minutes/45

→ time taken by 1 people = 20 minutes/3

time taken by 20 people = 20 minutes/3 × 20

→ time taken by 20 people = 400 minutes/3

→ time taken by 20 people = 133.3minutes

→ time taken by 20 people = 2 hours 13.3 minutes

time taken by 20 people is 2 hours 13.3 minutes
