### Problem Statement on Constant Speed Driving**1. A car starts driving at noon (t = 0) and drives at exactly 50 miles per hour until 4 pm (t = 4).****(a) How far does the car drive in that time?***Solution:* To determine the distance driven, use the formula:\[ \text{Distance} = \text{Speed} \times \text{Time} \]In this case, the speed is 50 miles per hour, and the time is 4 hours (from noon to 4 pm).\[ \text{Distance} = 50 \, \text{miles/hour} \times 4 \, \text{hours} = 200 \, \text{miles} \]So, the car drives **200 miles** during this time period.**(b) Sketch a graph of the car’s speed (in miles per hour) vs its time (in hours). Shade in the area below your graph, between t = 0 and t = 4.***Explanation:* The graph of the car's speed vs time is a horizontal line because the speed is constant at 50 miles per hour. The x-axis represents the time (t) in hours, and the y-axis represents the speed (s) in miles per hour.**Drawing the Graph:**1. Draw the time axis (horizontal) from \( t = 0 \) to \( t = 4 \).2. Draw the speed axis (vertical) up to at least 50 miles per hour.3. Plot a horizontal line at \( y = 50 \) from \( t = 0 \) to \( t = 4 \).**Shaded Area:**The area below the line (from \( t = 0 \) to \( t = 4 \)) and above the time axis represents the distance traveled. Since the car drives at a constant speed:\[\text{Shaded Area} = \text{Speed} \times \text{Time} = 50 \, \text{miles/hour} \times 4 \, \text{hours} = 200 \, \text{square units}\]This visual representation confirms that the car covers 200 miles.**Graph Details:**- The x-axis is labeled "Time (hours)" ranging from 0 to 4.-
