Answer:

Displacement, d = 4432.5 meters

Explanation:

It is given that,

Average velocity, v = -98.5 m/s

Time taken, t = 45 s

We need to find the displacement. Let it is d. It can be calculated as :


d=v* t


d=98.5\ m/s* 45\ s

d = 4432.5 m

So, the displacement of the flies is 4432.5 meters. Hence, this is the required solution.

Answer:

-4432.5 m . . . or . . . -4.4325 km

Explanation:

You can use the formula for average velocity, fill in the given values, and solve for displacement.

average velocity = displacement/time

-98.5 m/s = displacement/(45 s)

Multiply by time:

(-98.5 m/s)(45 s) = displacement = -4432.5 m

Keeping units with the numbers serves as a check on the math. (m/s)·s = m. The units work the same way variables do: they can be multiplied and divided, raised to a power, canceled. If the units of the problem don't work out right, you're probably doing it wrong. (Note, you can only add and subtract numbers that have the same (identical) units--the same rule as for combining like terms.)
