Question
There is a circular track of length 400m. If you cover 270∘ of the track, what is the length you have covered while running?
Answer: Option C
:
C
If you cover 360∘ of the track , the length covered = 400m
So,
For 180∘, the length covered will be
=12(400m)=200m
For 90∘, the length covered will be
=12(200m)=100m
∴ For 270∘, the length covered = length covered for 180∘+ length covered for 90∘
=200m+100m=300m
