Answer:
87.5 mph
Explanation:
All you need to do is find the car's acceleration rate.
Acceleration = ending speed - starting speed divided by the time it takes.
The top equation is finding the car's acceleration rate and the bottom equation is finding the answer to the question.
[tex]a=\frac{v_{2} - v_{1}}{t} = \frac{60-0}{8} = 7.5mph\\\\v_{2} = at + v_{1} = (7.5)(5) + 50 = 87.5[/tex]
Hope this helps! Good luck :)
