A cyclist moving on a circular track of radius 100 meters completes one revolution in 2 minutes. What is the average speed of cyclist (approx.)?

1314 m/min
2200m/min
3300 m/min
4900 m/min

Answer:- 1

Explanation:-

Solution:

Distance covered in one complete revolution

\begin{aligned} = 2 π r \\ = \frac{2 \times 100 \times 22}{7} \\ = 628 m \\ Average speed \\ = \frac{628}{2} \\ = 314 m / min \end{aligned}

$\eqalign{ & = 2\pi r \cr & = \frac{{2 \times 100 \times 22}}{7} \cr & = 628\,m \cr & {\text{Average}}\,{\text{speed}} \cr & = \frac{{628}}{2} \cr & = 314\,m/\min \cr}$
