Answer:
Average speed of the racer is 5.8 m/s.
Explanation:
Total distance covered by racer = D = 406 m
Total time taken racer= T = 70 seconds
The formula of an average speed is given by:
Average speed :
\(=\frac{\text{Total distance covered}}{\text{Total time taken}}=\frac{D}{T}\)
Average speed of the racer is:
\(=\frac{406 m}{70 seconds}=5.8 m/s\)
