Question

Is Arnaldo's estimate of running an average of 104 meters in 1 minute reasonable based on his running distance of 5,175 meters in 4.5 minutes? Provide an explanation for your answer.

Answer 1

Arnaldo's estimate of running 104 meters per minute is not reasonable because his actual average speed was calculated to be 1,150 meters per minute, which is much higher than his estimate.

Step-by-step explanation:

To determine if Arnaldo's estimate of running an average of 104 meters in 1 minute is reasonable, we need to calculate his actual average speed based on the distance covered and the time taken. He ran 5,175 meters in 4.5 minutes, so we divide the distance by the time to find his speed.

Speed = Distance ÷ Time = 5,175 meters ÷ 4.5 minutes = 1,150 meters per minute

Comparing this to Arnaldo's estimate of 104 meters per minute, we see that Arnaldo's estimate is significantly lower than his actual performance. Therefore, his estimate is not reasonable.
