Question

When taking a long road trip, plan rest stops before you leave - at least once every __________

Answer 1

I think the correct answer would be option B. When taking a long road trip, plan rest stops before you leave - at least once every  two hours or 100 miles. In this way, you would be awake for the whole road trip. Also, you can attend to your personal needs like eating and going to the bathroom. Also,  with this you would be able enjoy more of your trip, you would be able to see certain scenery closely and clearly rather than going on the road trip continuously until you reached your destination where in the long run you would just be bored and be sleepy.
