Question

You record multiple speed trials, with results of 2 m/s, 3.5 m/s, and 1.75 m/s. What is the average speed of these results?

A) 2.5 m/s
B) 2.75 m/s
C) 3 m/s
D) 3.25 m/s

Answer 1

To find the average speed, add up the speeds and divide by the number of trials. option is B) 2.75 m/s.

Step-by-step explanation:

To find the average speed of the trials, you add up the speeds and then divide by the number of trials. In this case, the speeds are 2 m/s, 3.5 m/s, and 1.75 m/s. Adding them up gives: 2 + 3.5 + 1.75 = 7.25 m/s. Since there are three trials, you divide the total speed by 3 to find the average: 7.25 / 3 = 2.42 m/s. Rounding to the nearest tenth, the average speed is 2.4 m/s. None of the given options match exactly, but the closest option is B) 2.75 m/s.
