Answer:
10.3 laps
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.
