Question

The time that a traffic light remains yellow is 1 second more than 0.05 times the speed limit.

1. Write an equation that represents Y, the length of the time the light is yellow at x miles per hour.

Answer 1

Explanation:

Let's use the variable Y to represent the length of time (in seconds) that the traffic light remains yellow at a speed of x miles per hour. According to the information given, the time the light is yellow (Y) is 1 second more than 0.05 times the speed limit (x). We can write this as:

Y = 0.05x + 1

In this equation:

Y represents the length of time the light is yellow in seconds.

x represents the speed limit in miles per hour.

The equation shows that the time the light is yellow increases linearly with the speed limit, with an additional 1-second buffer.
