Answer:
The school ended at 3:20 pm.
Step-by-step explanation:
Given:
Time Yasmin arrived home =4:25 pm
Time to walk home = 15 mins;
Practice begins = 20 mins after final bell
Practice lasted for = half hour.
We need to find when did the school ended.
Solution:
First we will calculate the time for all the activities.
Time to walk home = 15 mins;
Practice begins = 20 mins after final bell
Practice lasted for = half hour.
Now we know that;
1 hour = 60 mins
half hour =
Practice lasted for = 30 mins.
Total Activity time = Time to walk home + Practice begins + Practice lasted for.
Total Activity time =
Now we know that
60 mins = 1 hour
65 mins = 1 hour and 5 mins
Now we can say that;
Time at which school ended is equal to Time Yasmin arrived home minus Total Activity time.
So we will subtract 1 hour and 5 mins from 4:25 pm we get 3:20 pm.
Hence The school ended at 3:20 pm.
