同学你好~
首先travel不一定是指我们中文中说的旅游哦，很多中文翻译其实是有点模糊的，当我们把travel用作动词时，更多的意为从A点到B点，可参考英文释义：
VERB
1. go from one place to another, typically over a distance of some length.
the vessel had been traveling from Libya to Ireland ·
2. (of an object or radiation) move, typically in a constant or predictable way.
light travels faster than sound

synonyms:
move · proceed · progress · advance · be transmitted · carry

再体会下 例如：
I travel by car when I go to work.
我开车去上班。
He travelled 30 kilometers to get to the hospital.
他走了30公里才到达医院。

因此其实这个回答不跑题~
