​A cyclist covers a distance of 750 m in 2 min 30 sec. What is the speed in km/hr of the cyclist?

Correct option is A

Given:

Distance = 750 m

Time = 2 min 30 sec = 150 seconds

Formula Used:

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

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

Solution:

Speed = $$\frac{750}{150} = 5 \text{ m/sec}$$​​

In, km/hr

Speed = $$5 \times \frac{18}{5} = 18 \text{ km/h}$$​​
