A jogger runs at an average speed of 5.9 mi/h. If she starts a run at 11:15 am, what time is it after she covers 4.75 x 104ft?
To determine the time it takes for the jogger to cover a distance of 4.75 x 10^4 ft, we need to convert the distance to miles.
Given: 1 mile = 5280 ft
4.75 x 10^4 ft = (4.75 x 10^4) / 5280 miles
= 9.00 miles (rounded to two decimal places)
To calculate the time, we can use the formula:
Time = Distance / Speed
Time = 9.00 miles / 5.9 mi/h
= 1.525 hours (rounded to three decimal places)
Now, we add this time to the starting time of 11:15 am.
11:15 am + 1.525 hours
To add hours to a time, we convert the hours to minutes and add them to the minutes part of the time.
1.525 hours = 1 hour and 0.525 hours
0.525 hours x 60 minutes/hour = 31.5 minutes
So, the time taken is approximately 1 hour and 31.5 minutes.
Adding this to 11:15 am:
11:15 am + 1 hour = 12:15 pm
Then,
12:15 pm + 31.5 minutes = around 12:46 pm
Therefore, it would be approximately 12:46 pm after she covers a distance of 4.75 x 10^4 ft.
To find the time it takes for the jogger to cover a certain distance, we can use the formula:
Time = Distance / Speed
First, we need to convert the distance from feet to miles since the jogger's speed is given in miles per hour. There are 5,280 feet in a mile, so:
Distance in miles = (4.75 x 10^4) / 5280
Distance in miles ≈ 8.98 miles
Now, we can calculate the time using the formula:
Time = Distance / Speed
Time = 8.98 miles / 5.9 mi/h
Time ≈ 1.52 hours
Since we want to find the time after the jogger starts at 11:15 am, we add the calculated time to the starting time.
11:15 am + 1.52 hours = 12:45 pm
Therefore, it would be approximately 12:45 pm when the jogger covers a distance of 4.75 x 10^4 feet.
I would convert 5.9 miles/hour to feet/hour (there are 5,280 feet in a mile) , then use
distance = rate x time
solve for time in hours and add to 11:15 A. M.
