1. The problem statement, all variables and given/known data

4. A bee flies a distance of 2m in only one-quarter of a second.
(a) From the ratio 2/(1/4) , what can you infer about the bee’s motion?
(b) From the ratio (1/4)/2 , what can you infer about the bee’s motion?
(c) In one eighth of a second, what would be the distance that the bee has flown?
(d) How long does it take the bee to fly 10m?

2. Relevant equations

speed = distance travelled / time

3. The attempt at a solution

a) ... it gives the average speed of h bee's travel.. i think?
b) ... i have no idea
c) i use the average speed to calculate it
d) i also use the average speed to calculate it

a) looks right... the average speed of the bee is 2/(1/4) = 8m/s

For b) 2/(1/4) gives the number of meters travelled per second... so what does the reciprocal give: 1/4/2... the units are seconds per meter...

c) d = v*t. use the speed from part a)

d) again use d = v*t, using the speed from part a).
