Answer:
We can use trigonometry to solve this problem. The horizontal distance covered by each rider can be found by multiplying the distance they rode by the cosine of the angle of incline. The difference between the two distances will be the amount by which Jake covered less distance than Rafael.
For Jake:
Horizontal distance = distance * cos(angle of incline)
Horizontal distance = 100 ft * cos(7.9°)
Horizontal distance = 100 ft * 0.9925
Horizontal distance = 99.25 ft
For Rafael:
Horizontal distance = distance * cos(angle of incline)
Horizontal distance = 100 ft * cos(18.3°)
Horizontal distance = 100 ft * 0.9475
Horizontal distance = 94.75 ft
Difference in horizontal distance = 99.25 ft - 94.75 ft
Difference in horizontal distance = 4.5 ft
Therefore, Jake covered 4.5 ft more horizontal distance than Rafael. The closest option is A. 4.1 ft, but that is not the exact answer.
