Correct Answer: 40 km/hr
Solution :
There are 4 members.
Each member has to cover 5 km one after another.
⇒ Total distance covered by the 4 members = 5 $×$ 4 = 20 km
Total time taken = 30 min = $\frac{1}{2}$ hour
$\therefore$ Average speed $=\frac{\text{Total distance}}{\text{Total time}}= \frac{20}{\frac{1}{2}}=20\times 2 = 40$ km/hr
Hence, the correct answer is 40 km/hr.
