Answer:
<span>the speed of the car after it is increased by 20%
</span>
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 :)
