Goran cycled a total of 23.1 mi in 7 laps.
Then, we can use the next expression:
23.1 mi / 7 = 3.3 mi
Hence, each lap has a length of 3.3 mi.
Now, we need to convert mi( miles) to feet:
Use the rule of three:
If 1 mile is equal to 5280 feet, then 3.3 miles is:
1 mi ------------ 5280 ft
3.3 mi ------------- x ft
x= (3.3 mi* 5280 ft) / 1 mi
x= 17424 ft
Hence, the answer is 17424 ft.
