A car is traveling at a speed of yy miles per hour. Which situation would be described by the expression 1.2y1.2y? the speed of
the car after it is increased by 2% the speed of the car after it is increased by 20% the speed of the car after it is increased by 0.2 miles per hour the speed of the car after it is increased by 2.0 miles per hour?
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%
