During a vacation trip, Laura and her family decided to travel by car. The distance they will travel is directly proportional to the time spent on the trip. Laura noticed that after 2 hours, they had traveled 120 km. If the speed remains constant throughout the trip, what is the first-degree equation that represents this situation, considering d as the distance traveled in km and t as the time in hours?
d = 60t
d = 120t
d = 30t
d = 90t
d = 50t

Question 1:


Considering that you are a civil engineer responsible for designing a parabolic bridge that crosses a river, you need to determine the maximum height that the bridge can reach. When performing preliminary calculations, you discover that the bridge follows the equation of the parabola y = -2x² + 10x - 6, where y is the height (in meters) and x is the distance (in meters) from the starting point of the bridge. What is the distance at which the bridge reaches its maximum height?
