Explanation:

Hey there!!

Given,

acceleration (a) = 5 mi/hr^2

Initial velocity (u)= 45mi/hr

Time (t) = 4 hrs.

Now,

Final velocity (v) =?

We have,


a = (v - u)/(t)

Putting their values,


5 = (v - 45)/(4)

Simplifythem.

20 = v - 45

v = 65.

Therefore, the finalvelocity is 65mi/hr.

Hope it helps....
