In Chapter P, we see the usage of linear equations and graphs to solve real life problems. In this case, my project was based on Astronomy. I am suppose to use the linear equation d= r X t (distance= rate X time) to make the calculations with r= 186,000 miles/second. The planet I chose to do was Venus, so for the problem I just searched up the distance from the Moon to Venus, how fast the light travels from Venus to the Sun, and how long it takes for light to travel from the Sun to Venus. Using the information i searched up, I just plugged in the numbers to get my answer.
