Question

Mr Farah runs 10,000m in 13 minutes. What is his speed in m/s?

A) 3.85 m/s
B) 5.77 m/s
C) 9.62 m/s
D) 15.38 m/s

Answer 1

Mr. Farah's speed is calculated by dividing the distance he ran, 10,000 meters, by the time it took, which is 13 minutes or 780 seconds. After conversion, his speed is 12.82 m/s, which doesn't match any of the provided options.

Step-by-step explanation:

First, we need to calculate Mr. Farah's speed in meters per second (m/s). To do this, we will use the formula for speed which is distance divided by time. Mr. Farah ran a distance of 10,000 meters in 13 minutes. To work with SI units, we must first convert the time from minutes to seconds.

13 minutes is equal to 13 × 60 seconds, which is 780 seconds.

Now, divide the distance by the time to find the speed:

Speed = 10,000 m / 780 s = 12.82 m/s

Therefore, Mr. Farah's speed is 12.82 meters per second, which is not one of the provided options, suggesting a possible error in the question or the answer choices.
