Answer 1

Answer:
the speed of the car after it is increased by 20%

Step-by-step explanation:
We are given that the speed of the car is y miles per hour.
Now, 1.2y can be expressed as follows:
1.2y = y + 0.2 y
which is equivalent to:
1.2y = y + 20%y

Since y is the speed, based on the above, we can infer that the speed of the car increased by 20%

Hope this helps :)
