Answer:

11.9 miles

Step-by-step explanation:

The length of the track is ...

C = 2πr = 2π(200 ft) = 400π ft

Then the length of 50 laps will be ...

50C = 50·(400π ft) = 20,000π ft ≈ 62,831.9 ft

The number of miles (m) this is can be found from ...

m(5280 ft) = 62,831.9 ft

m = 62,831.9/5280 ≈ 11.90 . . . . miles

50 laps is about 11.9 miles.
