Hello!

First, remember that speed is a variation of position compared to a variation of time. It can be determined using the following formula:

v = Δx/Δt

where

Δx = variation in position

and

Δt = variation in time

If you know the speed and the time variation, you can isolate the displacement variable using the formula previously mentioned, like this:

Δx = Δt × v

Finally, you can replace the variables with the data provided to you!

I hope you found my answer helpful, do not hesitate to ask more questions!
