Answer:
28.5714m/s East.
Explanation:
-Velocity is defined as directional speed and is calculated as the quotient of displacement over time.
-Given the displacement as 100.0m and the time for that displacement as 3.5seconds and the direction as east, the velocity is calculated as;
![v=(d)/(t)\\\\v=(100.0m)/(3.5s)\\\\v=28.5714\ m/s \ East](https://img.qammunity.org/2021/formulas/mathematics/college/g4r0f6wgor7d5q5tfgjuhazg4358b8nlws.png)
Hence, the cyclist's velocity is 28.5714m/s East.
