Question

which has a greater speed a heron hat travels 600m in 60 seconds or a duck that travels 60 m in 5 seconds? Explain

Answer 1

The duck at 12m/s has a greater speed than the heron which travels at 10m/s

Answer 2

Answer:

The speed of duck is greater than the speed of heron.

Explanation:

$Speed(S)=\frac{Distance(D)}{Time(T)}$

Speed of heron : S

Distance covered by herons in 60 seconds = 600 m

D = 600 m . T = 60 seconds

$S=\frac{600 m}{60 s}=10 m/s$

Speed of duck : S'

Distance covered by herons in 5 seconds = 60 m

D' = 60 m . T' = 5 seconds

$S'=\frac{60 m}{5 s}=12 m/s$

12 m/s > 10 m/s

S' > S

The speed of duck is greater than the speed of heron.
