The average speed of a runner who runs 500.0 m in 1.3 min is 6.41 m/s.

The answer depends on the distance for the race. A marathon runner could not maintain the speed attained by a sprint runner.
Magnitude of average acceleration = (change of speed) divided by (time for the change)Average 'A' = (6 - 4) / 20 = 2/20 = 0.1 meter per second2-- That's the average over the 20 seconds. We don't know anything about thevalue of the acceleration at any particular instant during the 20 seconds.-- We're working entirely with scalars ... speed, not velocity, and magnitude ofacceleration ... since we don't know anything about the runner's direction atany time during the whole event.
The average speed of the runner is 1500m/(180 + 49.67) seconds = 6.531 m/s or 13 knots.
40 metres in 8seconds what would the speed be
Approximately 5.208 meters per second. Alternatively, 11.651 miles per hour.
3 km in 5 min => his average speed is 36 km in 60 min, that is 36 km per hour. Clearly an extremely fast runner and way faster than MY average speed.
