Answer:
4 hours and 24 minutes
Step-by-step explanation:
We just need to add all the time that Judy walked Monday and Wednesday. She walked 2 hours and 30 minutes Monday , which is a total of 150 minutes (2*60 + 30) and she walked 1 hour and 54 minutes on Wednesday which is a total of 114 minutes (60 + 54).
So she walked 150 + 114 minutes which is 264 minutes
Now we can convert this to hours and minutes by dividing by 60 and our remainder will be the leftover minutes. So 264 divided by 60 = 4 remainder 24
This means Judy walked for a total of 4 hours and 24 minutes
