7/2.5 = 2.8 hours
0.8 * 60 = 48 minutes
2 hours and 48 minutes
thank you!
You're welcome.
To find out how much time it takes Giita to walk 7 miles, we can use the given information that she walks 2 1/2 miles in one hour.
First, we need to determine how much time it takes her to walk 1 mile. We divide 1 hour by 2 1/2 miles:
1 hour / 2 1/2 miles = (1/1) hour / (5/2) miles = 2/5 hours per mile
Next, we can multiply the time it takes her to walk 1 mile by 7 to find the time it takes her to walk 7 miles:
(2/5 hours per mile) * 7 miles = (2/5) * 7 hours = 14/5 hours
Now we need to round the answer to the nearest second. Since there are 60 minutes in an hour and 60 seconds in a minute, we can convert the fraction of an hour to seconds:
(14/5 hours) * (60 minutes / 1 hour) * (60 seconds / 1 minute) = 14 * 60 * 60 / 5 seconds = 3024 seconds
Therefore, it takes Giita approximately 3024 seconds to walk 7 miles.
