(A) Amy, standing near a straight road, records the sound of the horn of a car traveling at a constant speed. The recorded frequency as a function of the car's position along the road for trials at different car speeds is accurately graphed below.

Answer choices: greater than, less than, equal to
The speed in trial U is ..... that in T.
The speed in trial Q is ..... that in other trials.
When the car is far away, the average of the frequencies moving in and out is ..... the frequency at rest.
The speed in trial S is ..... that in other trials.
The distance of Amy from the path in T is ..... in R.
The speed in trial T is ..... to that in R.
(B) Using the data on the figure, calculate the speed of the car in trial R. Use 340 m/s for the speed of sound.
I've been working on this problem for the last hour. Please help!!!
