v = at + v₀

20 m/s = (5 m/s²) t + 0 m/s

t = 4 s

A creature moves at a speed of 7.86 furlongs/fortnight (not a very common unit of speed). If 1.0 furlong = 220 yards 1 fortnight
AVprozaik [17]

Answer:

2 0.00130719 m/s

Explanation:

Now we have

7.86 furlongs/fortnight

7.86 x 220 yards / fortnight

1729.2yards / fortnight

1647.8 yards / 14 days

123.5yards / day

So

123.5 x 0.9144 meter / day

112.meters / day

=112.9meters / 86400s

= 0.001307m/s

If you had said "in one second" instead of "in a given amount of time,
then the word in the blank would simply be frequency.
