Answer 1

9514 1404 393

Answer:

  10.3 laps

Step-by-step explanation:

On each lap, Ashley runs two lengths of 100 m and the circumference of a 60 m circle. That circumference is ...

  C = πd

  C = π(60 m) ≈ 188.496 m

So, the length of one lap is ...

  2·100 m + 188.496 m = 388.496 m

The number of times around for 4000 m will be ...

  (4000 m)/(388.496 m/lap) = 10.30 laps

Ashley must run 10.3 times around in order to run a total distance of 4 km.
