Question

Arnaldo ran 5,175 meters in 4.5 minutes. He estimated that this means he ran an average of 104 meters in 1 minute. Is his estimate reasonable? Explain.

A) Yes, it's reasonable considering the distance and time.
B) No, it's too low for the given distance.
C) No, it's too high for the given distance.
D) Yes, it's high for the given distance and time.

Answer 1

Arnaldo's estimation of 104 meters per minute is too low because the actual average speed is 1,150 meters per minute when dividing a distance of 5,175 meters by a time of 4.5 minutes.

Step-by-step explanation:

The student's question is whether Arnaldo's estimate of an average of 104 meters per minute is reasonable based on running 5,175 meters in 4.5 minutes. To determine if the estimation is reasonable, we divide the total distance by the total time.

5,175 meters ÷ 4.5 minutes = 1,150 meters per minute.

Since 1,150 meters per minute is significantly more than 100 meters per minute, Arnaldo's estimate of 104 meters per minute is too low for the given distance and time. Therefore, the correct answer is:

B) No, it's too low for the given distance.
