Question 35

Connor's average speed was 18 miles per hour.

To calculate Connor's average speed, we first convert 55 yards to miles and then calculate the speed in miles per hour. Connor sprinted 55 yards in 6.25 seconds, which translates to an average speed of 18 miles per hour.

A) 6

This option is incorrect. A speed of 6 miles per hour is significantly lower than the calculated average speed. Given the distance and time, the average speed is much higher than this value.

B) 9

This option is also incorrect. Although 9 miles per hour is a possible speed for some short sprints, it does not reflect the calculations for Connor's sprint of 55 yards in 6.25 seconds, which yields a higher average speed.

C) 15

This option is incorrect. While 15 miles per hour is a reasonable speed for a fast runner, the calculation of Connor’s average speed shows that it is actually higher than this, confirming this option is not correct.

D) 18

This option is correct. The average speed of 18 miles per hour is derived from converting the distance of 55 yards to miles and dividing by the time taken in hours, confirming it is the accurate representation of Connor's performance.

E) 26

This option is incorrect. A speed of 26 miles per hour is unrealistically high for the given distance and time. The calculations clearly indicate that Connor's average speed is lower than this figure.

Conclusion

The calculations confirm that Connor's average speed is definitively 18 miles per hour, making option D the correct choice. All other options are either too low or excessively high compared to the actual calculated average speed based on the distance and time provided.
