Answer 2

Answer:

Option (c)  600 meters in 10 seconds is the correct option. or Option (a) 60 meters in 1 second.

Step-by-step explanation:

We know that speed = $\frac{Distance}{Time}$

Therefore, for part (a),

Speed = 60/1

           = 60 m/sec

Similarly, for part (b),

Speed = 60/5

           = 12 m/sec

Similarly, for part (c),

Speed = 600/10.            = 60 m/sec

Similarly, for part (d),

Speed = 600/60

           = 10 m/sec

It is clear that 60 > 60 > 12 > 10

Therefore,  the fastest speed is of : 600 meters in 10 seconds or 60 meters in 1 second

Therefore, the correct option is Option (c)  600 meters in 10 seconds or Option (a) 60 meters in 1 second
