Answer 1

Answer:

19.20 seconds.

Step-by-step explanation:

Given:

She invited 150 friends.

But she only had 5 activities for her friends and her party only lasted 4 hours.

Question asked:

How much time will each friend get on each activity ?

Solution:

First of all convert 4 hours into seconds:-

1 hour = 3600 seconds

4 hours = 3600 $\times$ 4 = 14400 seconds

By unitary method:

150 friends get time in 5 activities = 14400

1 friend get time in 5 activities = 14400 $\div$ 150 = 96 seconds

That means each friend get 96 seconds in all 5 activities.

Each friend get time on each activity = ?

Each friend get time on 5 activities = 96

Each friend get time on 1 activity = 96 $\div$ 5 = 19.20 seconds

Thus, each friend will get 19.20 seconds on each activity.
