After riding the bus, Tran walked 30 minutes to get to her friend's house. Her total travel time was 4 times as long as the bus ride. What equation does this situation model? Use t for the time of the bus ride.
Let t represent the time of the bus ride in minutes.
The time Tran walked to her friend's house is 30 minutes.
The total travel time is 4 times the bus ride:
t + 30 = 4t
Therefore, the equation that models this situation is:
30 = 3t
