Final answer:
Ann's trip, traveling 120 miles in 2 hours, indicates a speed of 60 miles per hour, therefore the correct equation for distance as a function of time is d = 60t. The options provided do not include the correct equation, but option A would be the closest if the factor were adjusted to 60.
Step-by-step explanation:
The question asks which equation can be used to show the distance, d, Ann will travel in hours, t, given that she has traveled 120 miles in 2 hours at a constant speed. To find the constant speed, we divide the distance by the time:
Speed = Distance ∕ Time = 120 miles ∕ 2 hours = 60 miles per hour.
Then, we can set up the equation for distance based on the speed and time:
d = 60t
Therefore, none of the options A, B, C, or D directly represents the correct relationship between distance and time for Ann's trip. However, if we were to choose the best fit from the given options, it would be A (d = 2t), although it would need to be adjusted to d = 60t to accurately depict the scenario.
