I am having problems coming up with the answer to this problem. Could you kindly help me. It took Amanda 3 hours and 20 minutes to drive from her home to a friend’s house. She
then drove to the beach which took her 4 hours and 25 minutes. It only took Amanda 5
hours and 35 minutes to return home because she took a shortcut. What was Amanda’s
total driving time?
Add:
3 hours, 20 minutes
4 hours, 25 minutes
5 hours, 35 minutes
3 20/60 + 4 25/60 + 5 35/60
200/60 +265/60 + 335/60
13 1/3 hr
Sure! To find Amanda's total driving time, we need to add up the time she spent driving from her home to her friend's house, the time she spent driving from her friend's house to the beach, and the time it took her to return home.
First, let's add up the time Amanda spent driving from her home to her friend's house. She took 3 hours and 20 minutes for this leg of the journey.
Next, let's add up the time Amanda spent driving from her friend's house to the beach. She took 4 hours and 25 minutes.
Finally, let's add up the time Amanda took to return home. She took 5 hours and 35 minutes.
To find the total driving time, we add these three amounts together:
3 hours and 20 minutes + 4 hours and 25 minutes + 5 hours and 35 minutes
To add time, we need to convert the minutes to hours. There are 60 minutes in an hour.
So we have:
3 hours and 20 minutes = 3 + 20/60 = 3 + 1/3 = 3 1/3 hours
4 hours and 25 minutes = 4 + 25/60 = 4 + 5/12 = 4 5/12 hours
5 hours and 35 minutes = 5 + 35/60 = 5 + 7/12 = 5 7/12 hours
Now we can add them together:
3 1/3 hours + 4 5/12 hours + 5 7/12 hours
To add fractions, we need to find a common denominator. The common denominator for 3, 12, and 12 is 12.
Converting the fractions to have a denominator of 12, we get:
3 4/12 hours + 4 5/12 hours + 5 7/12 hours
Now we can add the whole numbers and fractions separately:
3 + 4 + 5 = 12
4/12 + 5/12 + 7/12 = 16/12 = 1 4/12 = 1 1/3
Adding the whole numbers and fractions together, we get:
12 + 1 1/3 = 13 1/3
So Amanda's total driving time is 13 hours and 1/3 hour, or approximately 13 hours and 20 minutes.
