Final answer:
The time it takes for the tortoise to walk 62.5 meters at a speed of 5 m/min is calculated using the formula Time = Distance / Speed, which gives us 12.5 minutes.
Step-by-step explanation:
The question asks to calculate how long a tortoise walks in the desert if it walks at a speed of 5 m/min and covers a distance of 62.5 m. To find the time taken, we use the formula:
Time = Distance / Speed
Substituting the given values into the formula:
Time = 62.5 m / 5 m/min = 12.5 minutes.
Hence, the tortoise walks for 12.5 minutes to cover the distance of 62.5 meters, making option A the correct answer.
