The distance from my home to my friend's residence is 14 miles Step-by-step explanation: Let me clarify the solution process: - When heading to my friend's house, my driving speed is 35 miles per hour. - In returning home, the driving speed increases to 40 miles per hour. - The total duration of the trip was 45 minutes. - Our goal is to determine the distance separating my home from my friend's house. - First, we will convert 45 minutes into hours since the driving speed is expressed in miles per hour. Knowing that 1 hour equals 60 minutes, it follows that 45 minutes equates to hours. - Let’s assume that the distance between my home and my friend's place is d; thus, the time taken to reach my friend's house will be and the time for the ride back will be. Since the distance between the two is d, the corresponding equations will be: d = 35 ×, and d = 40 ×. - Setting both equations equal we derive:. - After dividing both sides by 35, it leads to. - This indicates that the total time of the round trip is hours. - Utilizing this information, we then substitute back into the equations to compute d, leading to the conclusion that the distance from my home to my friend's is indeed 14 miles.
