​A cyclist covers 650 m distance in 2 min 10 sec. Then the speed of the cyclist in km/hr is: ​

Correct option is A

Given:

Distance = $650\text{m}$

Time = $2\text{min}10\text{sec }=2\times 60+10=130\text{sec}$

Formula Used:

$$\text{Speed (in m/s)} = \frac{\text{Distance (in m)}}{\text{Time (in sec)}}$$

$$\text{Speed (in km/hr)} = \text{Speed (in m/s)} \times \frac{18}{5}$$

Solution:

Calculating speed in m/s:

Speed = $$\frac{650}{130}$$ = 5m/s

Converting to km/hr:

5 $$\times \frac{18}{5}$$ = 18km/hr​

Thus, option (A) is right.
