A cyclist covers a distance of 750 meter in 2 minutes 30 seconds. What is the speed in km/hr of cyclist.

1. 16 km/hr

2. 17 km/hr

3. 18 km/hr

4. 19 km/hr

Answer
Answer:18 km/hr
Explanation:

\begin{aligned} S p e e d = \frac{D i s t a n c e}{T i m e} \\ D i s t a n c e = 750 m e t e r \\ T i m e = 2 min 30 sec = 150 s e c \\ S p e e d = \frac{750}{150} = 5 m / s e c \\ => 5 * \frac{18}{5} k m / h r = 18 k m / h r \end{aligned}
