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
4 = 14400 seconds
By unitary method:
150 friends get time in 5 activities = 14400
1 friend get time in 5 activities = 14400
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
5 = 19.20 seconds
Thus, each friend will get 19.20 seconds on each activity.
