Final answer:
The total change in elevation of the tram is calculated by multiplying its speed (9 m/s) by the time it moved upward (27 s), resulting in 243 meters.
Step-by-step explanation:
The student's question involves calculating the total change in elevation of a tram moving at a constant speed upwards. To find the total change in elevation, we can use the formula for distance traveled, which is:
Distance = Speed × Time
We are given the speed of the tram as 9 meters per second and the time as 27 seconds. By multiplying these two values, we obtain the distance the tram has traveled upwards, which is also the change in elevation:
Distance = 9 m/s × 27 s = 243 meters
Therefore, the total change in the tram's elevation is 243 meters, which corresponds to option A.
