As part of an annual fundraiser to help raise money for cancer research Mary joined a walkathon the track she walked was on 770 yd long Mary walked 16 laps. Her sponsors agreed to donate an amount of money for each mile she walked how many miles did she walk
To find out how many miles Mary walked, we need to convert the length of the track and the number of laps into miles.
1 mile is equal to 1760 yards.
So, the length of the track in miles would be: 770 yards / 1760 yards/mile = 0.4375 miles
Mary walked 16 laps, so the total distance she walked in miles would be: 0.4375 miles/lap * 16 laps = 7 miles.
Therefore, Mary walked 7 miles.
