To find Alyssa's velocity relative to the ground, you can simply add the velocity of the train to Alyssa's walking speed, since both velocities are in the same direction (to the east).
The velocity of the train is 45 meters per second to the east, and Alyssa's walking speed is 2 meters per second also to the east.
So, the calculation is as follows:
\[
\text{Alyssa's velocity to the ground} = \text{Train's velocity} + \text{Alyssa's walking velocity}
\]
\[
\text{Alyssa's velocity to the ground} = 45 \, \text{m/s} + 2 \, \text{m/s} = 47 \, \text{m/s}
\]
Therefore, Alyssa's velocity relative to the ground is **47 meters per second to the east**.
The velocity of the train is 45 meters per second to the east, and Alyssa's walking speed is 2 meters per second also to the east.
So, the calculation is as follows:
\[
\text{Alyssa's velocity to the ground} = \text{Train's velocity} + \text{Alyssa's walking velocity}
\]
\[
\text{Alyssa's velocity to the ground} = 45 \, \text{m/s} + 2 \, \text{m/s} = 47 \, \text{m/s}
\]
Therefore, Alyssa's velocity relative to the ground is **47 meters per second to the east**.
