Question

Kristen ran at an average rate of 4.54 meters per second. If she ran for 420 seconds, how far did she run? A) 1906.8 meters B) 3.420 meters C) 4.432 meters D) 4.767 meters E) 4.921 meters

Answer 1

To determine the distance Kristen ran, multiply her average speed (4.54 m/s) by the time she ran (420 s), resulting in a total distance of 1906.8 meters, which corresponds to answer A.

Step-by-step explanation:

The student has asked how far Kristen ran if she had an average speed of 4.54 meters per second and ran for 420 seconds. To calculate the distance traveled, we use the formula distance = speed × time. We multiply Kristen's speed of 4.54 meters per second by the total time of 420 seconds.

Distance = 4.54 m/s × 420 s = 1906.8 meters

Therefore, the answer is A) 1906.8 meters.

Answer 2

Kristen ran 1906.8 meters by running at a speed of 4.54 m/s for 420 seconds.

Step-by-step explanation:

To determine how far Kristen ran, we need to multiply her average speed by the time she was running. Kristen ran at an average rate of 4.54 meters per second for a total of 420 seconds. To calculate the distance, we use the formula:

Distance = Speed × Time

So, the distance Kristen ran is:

Distance = 4.54 m/s × 420 s = 1906.8 meters

Hence, Kristen ran 1906.8 meters.
