Question

A plane flies with an average velocity of -98.5 m/s for 45.0s .What is the displacement?

Answer 1

-4432.5 m

Explanation:

distance (or displacement) = rate times time.

Here, the displacement is

(-98.5 m/s)(45.0 s) = -4432.5 m

Answer 2

-4432.5 m

Explanation:

Displacement is measured in meters, so will be the product of velocity in m/s and time in s.

(-98.5 m/s)×(45.0 s) = -4432.5 m

___

If you're concerned with significant figures, you can round this to -4430 m, which has the required 3 significant figures.
