Answers
Question : An athlete completes one round of a circular track of diameter 200 m in 40 s. What will be the distance covered at the end of 2 min 20 s?
Diameter of Circular Track = 200 meter
Radius = = 100.
The time taken for one round = 40 seconds.
Total Distance covered in one round = 2 pie r
= 2 × × 100
Speed =
=
Distance covered = Speed × Time
=
= 2200 meter.
Hence, the total distance covered by the athlete is 2200 meters.
Diameter of Circular Track = 200 meter
Radius = \frac{200}{2} = 100.
The time taken for one round = 40 seconds.
Total Distance covered in one round = 2 pie r
= 2 × \frac{22}{7} × 100
Speed = \frac{Distance}{Time}
= \frac{2 * 2200}{ 7 * 40}
Distance covered = Speed × Time
= \frac{4400}{7 * 40 * 2 * 60 + 20}
= 2200 meter.
Hence, the total distance covered by the athlete is 2200 meters.
