Answer:
The girls worked together on their art project for 1 hour and 50 minutes.
Step-by-step explanation:
In order to find the answer you have to find the difference between the time they began working and the tine they finished working. You have to subtract 3:25 from 5:15.
Since 25 minutes on the time they began working is higher than 15 minutes, you have to subtract 1 from the time they finished working that is 5 hours:
5-1=4
Then, you have to increase the minutes on the time they finished working by 60:
15+60=75
Now, you have to subtract the minutes which would be 25 from 75:
75-25=50
Finally, you have to subtract the hours which would be 4 minus 3:
4-3=1
The result would be 1 hour and 50 minutes.
According to this, the answer is that the girls worked together on their art project for 1 hour and 50 minutes.
