Answer 1

The correct situation based on the equation t + 20 = 45 is that Eric spends 25 minutes on the green line train and 20 minutes on the red line train for a total of 45 minutes commuting to his grandparents' place.

Step-by-step explanation:

The situation based on the equation t + 20 = 45, where t is the number of minutes Eric spends on the green line train, can be interpreted as follows:

Eric rides the green line train for a number of minutes represented by t, and then he rides the red line train for an additional 20 minutes. The total time spent commuting is 45 minutes. So, we need to find a situation where the sum of the time Eric spends on the green line train and an additional 20 minutes equals 45 minutes. To do this, we solve for t:

1. t + 20 = 45
2. t = 45 - 20
3. t = 25

Therefore, Eric spends 25 minutes on the green line train. Option D is the correct situation: To get to his grandparents, Eric rides the green line train for four stops. Then he rides the red line train for 20 minutes. In all, Eric spends 45 minutes on the trains.
