Improve Speed in 400m Dash: How Fast Can Sarah Go?

Calculating Sarah's Speed

Sarah, a track athlete, is currently running the 400m dash in 50 seconds. To determine her speed over this distance, we can use the formula for speed:

Speed (v) = Distance (d) / Time (t)

Given data:

• Distance (d) = 400m
• Time (t) = 50s

Plugging in these values into the formula, we get:

v = 400m / 50s

v = 8 m/s

Therefore, Sarah's current speed over the 400m distance is 8 meters per second.
