Question

There is a circular track of length 400m. If you cover 270${}^{\circ }$ of the track, what is the length you have covered while running?

• A. 100m
• B. 200m
• C. 300m
• D. 400m

Answer 1

The correct option is C

300m

If you run for 360${}^{\circ }$, length covered = 400m

For 180${}^{\circ }$, length covered = 200m

For 90${}^{\circ }$, we can now say that length covered will be 100m

So, for 270${}^{\circ }$ (180${}^{\circ }$ + 90${}^{\circ }$), length covered = 300m (200m + 100m)
