After riding on 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.

1 answer

Let's denote the time of the bus ride as \( t \) (in minutes). According to the situation described:

  1. The total travel time includes the time on the bus and the time Tran walked. The walking time is given as 30 minutes.
  2. The total travel time is stated to be 4 times as long as the bus ride.

Therefore, we can express the total travel time as the sum of the bus ride time and the walking time:

\[ \text{Total travel time} = t + 30 \]

According to the problem, the total travel time is also equal to 4 times the bus ride time:

\[ \text{Total travel time} = 4t \]

Now we can set up the equation:

\[ t + 30 = 4t \]

This equation models the situation described in the problem.
