Correct Answer: 3 m/s
Solution :
The total distance traveled = 20 m + 25 m = 45 m
The total time taken = 5 s + 10 s = 15 s
$\therefore$ The average speed $ = \frac{\text{Total Distance}}{\text{Total Time}} = \frac{45 \, \text{m}}{15 \, \text{s}} = 3 \, \text{m/s}$
Hence, the correct answer is 3 m/s.
