Answer:

Below

Step-by-step explanation:

First we will find the distance from when the bike is accelerating

Use this formula to find this :

d1 = ( vf - vi / 2 ) t

d1 = ( 5m/s - 0 m/s / 2 ) 4.5 s

d1 = (2.5)(4.5)

d1 = 11.25 m

Now we can find the distance for another 2.5 seconds

Since the car accelerated to 5 m/s, the constant velocity will be 5 m/s

Use this formula to find this :

d2 = vt

d2 = (5m/s)(2.5s)

d2 = 12.5 m

Finally we can add them up to get the total distance :

dt = 12.5 m + 11.25 m

dt = 23.75 m

*Make sure to round this number to how your teacher taught you

Hope this helps!
