<span>To tackle the above dilemma,

we utilize the formula speed = distance/time.

Observing the red line:/>A covers 8 miles in 60 minutes, thus his speed reaches 8 miles per hour while K manages 2 miles in 30 minutes, resulting in her speed of 4 miles per hour, with a 5-mile head start.</span><span>A's distance = initial gate distance + (speed x time)
A's distance = 0 + (8 x time)

K's distance = initial gate distance + (speed x time)
K's distance = 5 + (4 x time)

For them to have traveled equal distances from the gate, they must have caught up with each other.
Therefore, when:

A's distance = K's distance
0 + (8 x time) = 5 + (4 x time)
8t = 5 + 4t
8t - 4t = 5
4t = 5
t = 5/4 hours
t = 1 hour and 15 minutes
t = 75 minutes
</span>
The solution is option D. I hope this clarifies the issue.
