Answer:
It will take the marathon runner about 28.27 s to run 158 m at a pace of 5.5 m/s
Step-by-step explanation:
Time = Displacement / Velocity
Since everythign is already in the same terms (meters, adn seconds) we dont have to convert everything just plug it in
Time = 158 m / 5.5 m/s
time = 28.27 s
