Suzie drove her gravity-powered car in a race. Her winning time on the 325-meter course was 53.2 seconds.
Which average speed, in meters per second, is closest to Suzie's average speed during the race?
A 0.164 m/s
B 6.11 m/s
C 9.82 m/s
D 288 m/s
E 367 m/s
B is what i think
B is right.
Well, let's do some calculations together, shall we? Suzie covered a distance of 325 meters in a time of 53.2 seconds. To find her average speed, we need to divide the distance by the time.
So, 325 meters divided by 53.2 seconds gives us approximately 6.11 meters per second.
And guess what? You got it right, my answer-loving friend! The option B, 6.11 m/s, is indeed the closest to Suzie's average speed during the race. Good job! *clown bow*
To calculate Suzie's average speed, we can use the formula:
Average speed = Distance / Time
Given that the distance is 325 meters and the time is 53.2 seconds, let's plug in the values:
Average speed = 325 / 53.2 ≈ 6.11 m/s
Therefore, option B, 6.11 m/s, is the closest average speed to Suzie's during the race.
To calculate Suzie's average speed during the race, we need to divide the total distance she traveled by the time it took her.
Average speed (m/s) = Total distance (m) / Time (s)
In this case, the total distance Suzie traveled is given as 325 meters, and the time it took her is 53.2 seconds.
Substituting these values into the formula:
Average speed (m/s) = 325 m / 53.2 s
Now we can calculate the average speed:
Average speed (m/s) ≈ 6.11 m/s
Therefore, Suzie's average speed during the race is approximately 6.11 m/s.
As you correctly mentioned, option B, 6.11 m/s, is the closest average speed to Suzie's actual average speed during the race.
