Yasmin arrived home from play practice at 4:25 pm. The walk home took 15 minutes. Practice began 20 minutes after the final bell and lasted for a half hour

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.
