To solve this problem, we need to set up two equations based on the information given.

1. The first equation is based on the fact that Keith travels at a speed of 3 km/hr and arrives 15 minutes late. We can express this as: Distance = Speed * Time, or D = 3T. Since he is 15 minutes late, we can express the time as T = t + 15/60, where t is the actual time it should take him to travel the distance. Substituting this into the first equation gives us D = 3(t + 15/60).

2. The second equation is based on the fact that if Keith travels at a speed of 4 km/hr, he arrives 15 minutes early. We can express this as: D = 4T. Since he is 15 minutes early, we can express the time as T = t - 15/60. Substituting this into the second equation gives us D = 4(t - 15/60).

Setting these two equations equal to each other gives us 3(t + 15/60) = 4(t - 15/60). Solving for t gives us t = 1 hour.

Substituting t = 1 hour back into either of the original equations gives us D = 3(1 + 15/60) = 3.75 km or D = 4(1 - 15/60) = 3.75 km.

However, none of the options match this result. There might be a mistake in the problem or the options provided.
